How can people who love to take advantage of small things suffer big losses?

1, go to the supermarket to buy food, only buy bargains, but many bargains are about to expire and are not fresh. The problem of eating for a long time is coming. You can save a little money and spend a lot of money to treat diseases!

2, in order to be greedy and cheap, buy underwear or steal other people's clothes at the stall, thinking that they are cheap, but the underwear bought at the stall is not necessarily guaranteed, even being worn by others, and some still carry diseases. Once they suffer physically, they will spend money to treat diseases!

3, in interpersonal communication, always love to take advantage of small things, such as going out to eat with roommates, always being treated by others, and always eating others without buying fruit. It seems that taking advantage is actually a big loss. Let others know who you are, don't want to be friends with you, don't help you, and even hate that you are far away from you!

4, some people in the society are greedy and cheap, and many of them are cheated into pyramid schemes!
