I Regret Nothing

(I am a computer tech at an electronics retailer. A customer walks up to the counter.)

Customer: “Hi, I was wondering if you have [tuning equipment for a home theater system]?”

Me: “I would check with audio-video, down in the back.”

Customer: “Oh, I already did, they said you didn’t have it.”

Me: “Then we don’t have it.”

Customer: “Are you sure?”

Me: “Ma’am, if audio-video says we don’t have it, we don’t have it. They’re the ones who would know.”

Customer: “Oh, okay. Thanks…” *muttered as she walks away* “…for nothing.”
