(A regular buys the same bottle of liquor every couple of days and brings in just enough money to pay for the bottle. This week, we happen to get in “special edition” bottles and put them in place of the normal ones.)

Me: “That will be [price].”

(The customer hands me money and I give him a $5 in change.)

Customer: “Is this on sale or something? You gave me too much change!”

Me: “That’s a special edition bottle we got in. It’s actually cheaper than the normal one!”

Customer: “Well, it’s been [price] for six years! Why is it cheaper?!”

Me: “Well, at least it’s not more expensive?”

Customer: *muttering* “It’s been [price] for six years…”

Me: *speechless*
