I confess for the 2 years i worked in a famous fast food joint i used to spit on the burgers. put the buns down my pants and rub them on my cock..sometimes my ass...
i did this every working day and so did a few others.
We would put boogers in the salad,flip burgers using a shovel etc .
spit in drinks etc..
so my advice. NEVER insult anyone who serves you food. It just might be me next time.
