My husband works in Food Service as does my oldest daughter, they've both told me horror stories.
My oldest daughter works at 2 places, 1 is super anal about their cleanliness, the other place they tease her because of her hygiene standards, whence she now tells everyone not to eat there when she's not working.
My husband told me about a kid that used to pee in the chili at Wendy's, now I don't eat chili or soup anywhere I go.
People are nasty !!
