Customer: “What is this Blu-ray thing? Are they like movies?”

Me: “Well, ma’am, they are like DVDs, but with better graphics and sound. Let me show you this packet we have that explains it.”

(I show her the packet.)

Customer: “OK, well, do you have any movies that are 3-D?”

Me: “We have The Polar Express and the Hannah Montana concert, but those are not going to be near the quality that you see in the theaters.”

Customer: “Oh. What about holograms? Do you have any movies on holograms?”

Me: “What? No, those don’t really exist ma’am…”

Customer: “Oh. I’ll just come back later and check then.”
