There is a friend to open a shop, he often encounter customers use credit card payment, the world's most famous is the Visa (Visa company) and Mastercard (MasterCard), for example: card with a Mastercard logo, indicating that the card also performs the standard of the organization, the international credit card machines generally support both payment brands, Europe prefer Mastercard, American is Vsia.

Now foreign mobile payment also follow up, payment Mercadopago same kind of Alipay this place I appeared, the merchant can scan code in addition to the payment, it also comes with a small Bluetooth card, you can connect the phone credit card charges, local and international support most of the payment brands, but also for the merchant card with Mastercard standard consumer card.

In other words, holding this card can go to any local support payment Mastercard payment, credit card base to support local support, OK, today to talk about the things to come.

When my friend took the card to spend, and asked the cashier: whether to support Mercadopago payment? Cashier answer: no. Then my friend said, this card can not go out consumption.

Then I taught him to say, you can not say, you have to say there is no direct credit card on OK, yes, the card directly to her brush on OK, do not ask other people do not understand something, this card emblazoned with Mastercard , do not take the trouble to say whether support Mastercard, you give him the card directly to the brush can, because the basic support of many places.

Later, I learned a lot of people do not understand this, have encountered this sort of thing, I said, you still business it? Usually also collect other people's money, take the card out of their own consumption, but still do not know the common sense?

It's like, Alipay send you a printed words Mastercard debit card to you, then you go out, or the time to go to other countries to come up with, and asked the cashier support Alipay it? Or it is so and so the bank sent you a card with a Visa words to you, after you go out and ask the cashier if you support a certain bank card payment?

If you are ordinary people do not understand these no problem, you own a business in itself, you also use the credit card machine to the closing someone else's money, and then never thought this is how it's going?

I do not know why, I want to criticize these people, but then think about it, everyone has something do not understand, but if some common sense not to understand, then, really is a joke, just like I do not care to eat things, and sometimes some of the condiments I do not know what the name, then a little familiar with cooking could inconceivable, how this thing will not understand.

Calmly say, I like to toss website, you like to engage in the server, he likes to write code, if only an amateur, maybe some common sense you really do not know, for example, you like to play server is not it? Do you know Linux file operations knowledge of it? You appear to come into contact with the server, you appear to be business, there are always some knowledge that you do not know the details, you can say this person stupid it?

It is said that liberal arts students than science students stupid, bad science because science before transferring to liberal arts, more learn physics and chemistry concepts traveled the world, but more than a lot of silly science is biased people, and stubborn, of course, ARTS We are powerful talent is really strong! There are too many factors influence but inside, but I think, a good memory, understanding and good science students, liberal arts in general are not that bad, really bad, most people most of the others said good science, science is only partial and not very the good kind, because if it is very good that, in general liberal arts science is usually very good.

Well, from what I want to scold people stupid, to understand a process of others, I myself as a liberal arts science are poor people, but I still live very confident (feel good - -), because I know there is no natural stupid, just experiencing the problem, to say stupid and clever, in fact, and the degree of physical health also has a relationship, someone raise IQ by exercise, I believe that as long as the knowledge usually do not understand something, you can not explain a stupid person.

For other examples below:

For example, you do not understand this stuff, and you can learn through short-term or the long-term learning, but some things really need to use their brains to solve the matter, that is the difference between clever and stupid, so people generally do not use their brains to think, we will He said he stupid, indeed is the case.

For example, some people say that do not know how to take the subway, I can not understand, there are two meanings, the first is do not understand the destination station name, the second is completely do not know how to take, but look at the name of the station or you go there You will not learn about it? To look at look at the subway map not to understand it? Then someone immediately said to not learn, do not want to learn fear is not willing to observe ah, someone would certainly say that do not understand the language in a foreign country, in fact, take the subway, then know anything about the language does not matter.

Another example is the transfer of digital watch, or watch electronic watches and the like, and some people will not tune it a few keys, a maximum of six buttons, all by the next, can not transfer, directly say not. But just do not use their brains, perhaps you can press a button or press twice if possible, is not it? This is something moving about the brain may be able to solve it.

There are some people in the street and say hello to someone, that person is busy and people to talk about things, did not notice him, so he did not respond, then the people will beat a louder call, expressed dissatisfaction with this people think in the end there is no-brainer. . .

Life, your popularity, emotional, career and so on highly important matters, and reflect on these stupid little things out or clever does not matter much, really.

If it is a truly confident person, I will accept their imperfect these areas, and just laugh it off when others mention, not value.

A: why do you do when a comedian?

B: A lot of people laughed at me, so just charge them money.
