Only Half Listening

(I work at a pool. A customer is swimming with his grandson. He has just noticed we have turned off the slide and are a putting a lane rope in, ready for length swim.)

Customer: “Oh, my God! You are closing!”

Me: “Yes, at six pm, and then we go to lanes.”

Customer: “But it said you were open until seven!”

Me: “Not in half-term. We close the pool at six, then go into lanes.”

Customer: “But last week, you were open until seven!”

Me: “Yes, but this is half-term, so we are open at ten and shut at six.”

Customer: “But last week, you had half the pool roped off and were open until seven.”

Me: “Yes, that is because it was term-time and we had lessons. It is half-term.”

Customer: “Oh, is it half-term?”
