I've done ONE thing in my duration of 4 years at Arby's. We served a "Hot Ham and Cheese" and this lady came up yelling "why is my ham sandwich hot?" I said "ma'am it's a "hot ham and cheese" she yelled "I want a cold ham and cheese" I said "ok"
so I proceed to hawk a nice thick brown one in her "cold ham and cheese". lol

I know a buddy of mine pissed in the 5 gallon bucket of sliced pickles when he worked at MCD's. Of course they served the whole 5 gallon bucket because you couldn't smell it mixed with all that vinegar.
