"I am picturing myself standing up while peeing on the little speaker-thingy that's telling me not to stand while peeing."
I am picturing myself leaving the seat down so I don't *have* to listen to the little speaker thingy, peeing standing up, and not caring where it splashes if someone rigs a toilet that way.
They have a very weird solution to this "problem." If they really wanted to enforce it, they would just make toilets with lids that don't come up. For older toilets, superglue comes to mind.
