Yuck! This article debates the legal repercussions of placing body fluids and other assorted yummies in other people's food items. Is it a misdemeanor or a felony? It depends on where you live!
Once, I was in our local Pizza Cabana picking up an order. Behind the register, I could see the teen worker dropped one of the breadsticks he was about to bring out to the tables and accidentally stepped on it. He looked up at the manager inquiringly. The manager gave a slight nod. The young man picked up the breadstick, put it on top of the others and proceeded out to the tables.
I followed him.
The manager saw I was about to inform the customers at the table of what was transpiring. "(Name!) Get back here! What were you thinking!??"
Um, yeah, he was thinking he was following orders. What else happens at restaurants that is unseen and unrecorded for YouTube? Maybe we don't want to know, but we'd like someone ELSE to have an idea and minimize it. Yuck.
