Wouldn't recommend, but I've heard of customers putting dead roaches in their food, in order to fool restaurants. Most places will offer to replace and cover the meal.

Funny thing is a few months back At a Walmart I saw a Huge Roach crawl up the wall in the MacDonalds
I have also seen another Roach Crawl onto the little fries thing.
I stopped eating there since but I might use that to my advantage.
