Bird nest sellers are like legal scammers.

Selling crap to stupid people.

Well, looking at the bright side, stupid people deserve to get their money scammed.

I understand people who eat caviar or black truffle or drink expensive wine cause those are acquired taste, which if you like them and you spend loads of money on them, it is still worth it.

Bird nest on the other hand is literally tasteless so you can't even say it is an acquired taste. You are just crazy stupid spending loads of money to taste nothing while increasing the risk of diabetes and getting influenza.
