A co-worker of mine at the college told me she once had to go to the bathroom -- quite badly -- and the maintenance crew was cleaning it at the time. Thinking that she couldn't make it to the distant second women's bathroom, she went back to her secluded interior office, locked the door, and peed in a gimme sports water bottle. Then, after the janitorial people were done, she discreetly emptied the bottle and threw it away in a lidded trashcan in the hallway.
Later, she says, one of the guys from the lab came by and showed her his Cool New Water Bottle that "some idiot had just tossed in the trash."
She congratulated him on his excellent trashcan diving skills and he went happily on his way.
