If you were at a friends house for dinner and found a dead cockroach in your salad what would you do?!
Answers: I personally would freak out, and take my bowl to the kitchen and dump it. It would be rude, but I once found a worm in my salad and nearly puked. I'm no good at bugs and being polite, etc.
tell him and don't eat anymore..
I would freak out. then throw away the food.and tell the friend.
Tell them ...gently
I would probably scream and possibly vomit. I would never eat there again. You should tell them if you have not all ready because they need to exterminate.
