Flushin' Roulette
The dilemma faced when walking into the only available public toilet stall to see that is full of crap and paper and could quickly turn into a messy overflow if flushed.
I ran into the office bathroom, happy to see one of the stalls open, only to be forced into a game of "Flushin' Roulette" because of the clogged mess left behind from the previous guest. I closed my eyes and pushed the handle and was relieved to have "dodged the bullet" when it didn't overflow.
