I realize this is a older post, but felt I had to add to it. If you're grossed out by bottles of piss, never, I repeat NEVER work at a travel center or "truck stop". Its like piss-bottle-palooza. It always made me want to figure out which truck driver did it and throw the bottle at the side of their truck when people would leave those at the fuel islands. **off topic** when I worked at a "truck stop", the womens bathroom I was cleaning one time had a occupant that was discussing feminine hygiene with someone on her cell phone. She proceeded to explain that she "wasn't so fresh" and fogged the entire cubicle with summers eve feminine spray.
