Still better than a light sensor in a communal bathroom… outside of the stalls. That’s how it is at my workplace. If I spend a bit too long pooping, and nobody else comes in to poop at the same time, I end up in the dark. Then when I have to wipe, I have to either risk opening the stall door and wave into the room, with my dirty ass hanging out, hoping nobody happens to enter the bathroom at that time, or wait patiently for someone to come in and reactivate the light. Makes me wonder how blind people check their wiping: do they go on flavor or smell?
