My friend works at one of the most unsanitary dumps around, [location edited]. While it attracts tourists, locals know better than to venture into that steamy jungle of filth.
"One father's day, it was crazy busy and some guy came in saying he wanted an extra piece of toast. But it was busy, so, the owner just fished out an old piece of toast from the trash,(and this had other trash sitting on top of it) and warmed it over a little and served it!"
"You know the broom/mop closet? Yeah, well they keep opened meat like stew beef in there and whenever someone cleans the floor, the meat gets 'mop juice' all over it."
Sometimes, when I clean the grease trap, I find cigarretes, even condoms in there!
