This is actually realistic. I was in a laundromat once, and the lady who owned it was ready to shut down for the night. No one knew that, since she never posted her hours. She would just walk through the place barking “We’re closed, we’re closed!” Some helpful fellow suggested she put put up a sign to say when the place closes, and she snapped “I don’t need a sign! I know when I close!”
