(I’m working in the shop at the entrance/exit to the attraction.)

Customer: “Excuse me, where are the nearest toilets?”

Me: “Your best bet is to go back through then they’re in the cafe next door.”

Customer: “Back inside the park?”

Me: “Yeah, I’ll let you back through.”

Customer: “But then we won’t be able to get back out again, will we?”

Me: “I’m sorry?”

Customer: “If we go back through we won’t be able to get back out of the park again.”

Me: *trying not to smile* “I assure you, you will.”

Customer: “Wait, that was really stupid wasn’t it?”
