Sign..... are the boxes / bags / chopsticks stuff really really that expensive? You never see "we charge you 25c for spoon" in English places, why are Chinese stores sooooo cheap?
Eat salty fish you expect thirst... You open up a place, you expect people to use boxes / bags, take chopsticks /spoons/napkins ga la....
Those of you that are in the restaurant business, can you explain?
