Don’t Appreciate The Lack Of Appreciation

(After spending nearly 20 minutes summarizing the plot of various crime novels from memory, because the customer doesn’t want to read the back covers, I finally convince her to choose a book to purchase.)

Customer: “If I don’t like it, I’m coming back here to yell at you!”

Me: *confused, but using my cheery work voice* “Well, if you do like it, I hope you come back and let me know!”

Customer: “Why would I do that?”

(Apparently being mean is worth the trip, but being appreciative isn’t.)
