Insects Should Not Be On The Menu
Insects have been in the trash maybe even dog poop and other disgusting.
If the insects have been in trash and other disgusting places I wouldn't think that would taste good. Some people wouldn't like it on the menu and think of it as ugly disgusting dirty insects and would come to the restaurant.
They can be expensive.
Some people wouldn't buy it because it's too expensive and they wouldn't want to spend it eating insects. Also they might not have enough money.
