I was waiting to use the bathroom in a big box store. There were only 4 stalls. The toilet in the first one was not flushed and TP was hanging out of the toilet. The next two were occupied - mother in one and young boy in next. Fourth and handicapped stall was taped shut with sign saying out of order.

The boy exited his stall first and I was about to go in and saw he had not flushed. I said to him “please flush” about the same time his mom was exiting her stall. He said “I can’t” as the mom looked at me like I was pure evil. I said “push the little black button” and he figured it out.

For context he was probably at least 6 or 7 years old and I would assume had flushed toilets in his young life.

Afterwards I kept seeing them in the store so I hid for a while.

I still feel like a jerk.
