(We have a 5-item max policy for our changing rooms. One lady walked out with arms full of stuff, then went back for more.)

Me: “Excuse me, it’s only 5 items in the changing rooms.”

Customer: “Well, it’s never been that before.”

Me: “Actually, we’ve been enforcing it for the last 18 months. See, there’s a sign.” *points at sign on wall*

Customer: “I don’t actually read signs.”

Me: “Well, at least you’ll know for next time.”

Customer: “Oh, I won’t read it next time, either.”
