Look, it's like this. This is the way I would like transactions to function.
You have some stuff. I have some money. I will give you some money if you give me some stuff. I don't want to be your friend, I don't want to join a club, I don't want a 3 % discount, I don't want to sign up for the lucky draw, I don't want a hong bao. I don't want to download your app. You give me some stuff, here's some money. 结束了。
