Trickle Toilet

I was waiting in a public restroom that had only 1 stall.

The stall door was closed and I could hear a gentle stream of water.

I stood there for a while and thought, "Gee, this person has been peeing for a really long time."

Eventually I realized the stall was empty and the toilet was leaking.

I was tricked by a porcelain bowl with a gift for mimicry.
