When i was working at a restaurant that shall remain nameless, a few years ago this lady found a clump of weed in her salad during lunch.
She was actually a really good sport about she joked that we put in there so she would get the munchies and eat more. Turns out one of our fry cooks was packing his pipe w/ weed the night before and i guess lost a few chunks in the salad bin. wouldnt have believed it if i hadnt been there!!!
