(I’m the Lifeguard on duty at an indoor pool when there’s a power outage. I must close the sauna for ventilation reasons. I enter, and a customer is sitting inside.)

Customer: “Close the door! You’re letting the heat out!”

Me: “Excuse me, sir, it is not safe for you to remain in the sauna because there is no longer adequate ventilation.”

Customer: “It’s a f***ing sauna! There’s not meant to be ventilation, so shut the d*** door!”

Me: “Without proper ventilation, the sauna will overheat and put you at risk for heat stroke.”

Customer: “That’s what lifeguards are for!”
