Merchants know that crabs are short of weight, but they take advantage of the loopholes in the app. Merchants bet that most consumers will not determine the weight of crabs. Mr. Wu calculated an account, because crab cakes are really affordable and many consumers buy them. Most consumers think that they are cheap and will not confirm whether these crabs are enough. That is to say, even if half of the consumers find the weight problem, they just make up the weight or refund the money, which has not caused any loss to the merchants at all. On the contrary, if consumers don't find out, businesses will earn about half more money.
After Mr. Wu spread this story to the Internet, it resonated with netizens. Most netizens have also been cheated on the app, but the final compensation is only a refund or replenishment. The price paid by merchants is very small, which is not enough to deter these unscrupulous merchants. Every year in the crab season, these businesses will still do the same thing and make black-hearted money.
Mr. Wu said that the exposure of this incident was mainly to make more people stop being deceived and not be greedy and cheap like him.
