Customer: “Hey, I believe I was charged the wrong price for this item. Could you refund it to me?”

Me: “Oh, of course, ma’am. Let me just see the receipt and I’d be happy to.”

Customer: “Here it is.”

(The customer hands me a receipt that is over three feet long and totals over $300.)

Me: “All right, which did you believe you were over-charged on?”

Customer: *points out three items*

Me: “Ma’am, it seems that you were charged an extra two cents for these two items here. Do you really want me to refund you the two pennies?”

Customer: “YES! And to be sure I want you to return and re-ring my purchase to make sure.”

Me: “Okay.”

(20 minutes later, after re-ringing her entire purchase, I let her know that she’ll be getting two pennies back.)

Customer: “What?! Why did you even do that if it was only two cents?! How stupid can you be?”

Me: “Um, ma’am, I informed you that you’d only get the two pennies back before I did the transaction.”

Customer: “No you didn’t! I can’t believe the incompetence of the people working here!”

(She takes her bag and walks out of the store, yelling obscenities the whole way.)
