"Are the bathrooms open?"
I guess I need to contextualize that a bit.
I'm working for the company my parents work at this summer for a part-time thing, because the business next door was going out of business and they bought the fixtures in the store and someone needed to go tear it down. The store's still open, but they're moving product near the entrance to give us room to break things down.
Because of all this, the bathroom in the store, way in the back, by where we're working most of the time, is shut down. So people realize there's no public bathrooms, they put a sign on each door AT EYE LEVEL saying that the bathrooms are closed. In case that wasn't obvious enough, we also got a taller-than-I-am sign, spraypainted in giant red letters "BATHROOM CLOSED", and hung this sign on the AISLE we used to completely block BOTH bathroom doorways, after COMPLETELY OBSCURING BOTH DOORS with PANELS OF WALL.
And yet we still got asked that question at least twice daily.
GOD, people are fucking stupid.
