Greeted by loud metal-on-metal crashing sounds from one of the stalls. Sound stopped, I think when the person realized there was someone else in the restroom, then resumed a few seconds later, accompanied by grunts.
“Are... you all right in there?” I asked.
Crashing stopped. “Yeah,” he answered. “I’m having trouble with my belt.” And the crashing resumed, continued until I left the restroom a couple minutes later.
