Sadly Not A Regular Occurrence

We have a very friendly regular who seems to buy books by the metre. She seems to be lost in a book when I approach her.

Me: “Sorry, [Regular], we’re closing in five minutes. Want me to check out the books in your bag while you decide on that last one?”

Regular: “I don’t think I can decide in five minutes. I’ll just come back.”

Me: “Yeah, I don’t want to rush you, but we do have to lock the doors soon and I don’t want to accidentally lock you in here all night.”

The regular then starts looking around the store longingly.

Me: “You’re imagining being locked in here all night, aren’t you?”

Regular: “Did I look that happy?”

The regular did leave, sadly, at closing time. She was back the next day to buy the book!
