(During the Christmas rush, a customer comes into my line talking on her cell phone.)

Me: “Hello. Would you like a protection plan with this?”

(Customer ignores me.)

Me: “Do you have a rewards card with us, ma’am?”

(Customer continues to ignore me.)

Me: “Okay, here’s your receipt. Have a nice day!”

(Customer stops talking on her phone and looks at me.)

Customer: “What about my rewards card?”

Me: “Well, I asked you if you had one, but you were too busy talking.”

Customer: “So you’re saying it’s my fault?”

Me: “Yes.”
