(Our tea shop closes at 9pm. The time is currently 9:10. There is one couple and their child still in the store. I am cleaning the bathroom. The customer opens the bathroom door.)

Me: “I’m sorry, I’m cleaning this bathroom.”

Customer: “But my son has to go.”

Me: “I’m using bleach, it’s very dangerous here. I can’t let you use the bathroom.”

Customer: “But my son has to go!”

Me: “I can’t let you use it. We’re already closed and I have to finish cleaning.”

Customer: *to another employee* “Your crazy cleaning lady won’t let my son use the bathroom. Can I speak to your manager?”

Co-worker: “That was the manager.”

(The customer silently grabs his wife and son and walks out without another word.)
