<human>: When I was a child I had the chance to visit a kiosk selling ancient Egyptian replicas and memorabilia.  My family was not to far away at another kiosk looking at potential gifts to buy for friends, so I was alone. At the time I had a large obsession with ancient Egypt so I had a strong desire to buy something with all my accumulated saved money (some 20 dollars). You had small statues of different gods, papyrus paintings, The Book of the Dead, among other things. It didn't matter what I would get, so long as I left the place buying something.

A salesman noticed my interest and asked me what I was interested in. I told him something genuine if possible, though I didn't have much money. He picked up a small pyramid that had your typical Egyptian-wall painted panels and handed it to me. He told me to shake it and asked if I heard the sand locked inside the pyramid. I could hear it and asked what was so important about it. He said that the sand was actually shaved off the famous pyramids of Giza and that I was holding an actual piece of history. I gleefully handed him my money and ran off happy as a kid could be.

Naturally this couldn't be so given the actual poor quality of the item I bought and the fact that a sticker plastered on the bottom of the pyramid had "Made in Vietnam" written on it. I only discovered this when I got older and found the pyramid locked away in an old box I had.

It still bothers me today that this salesman took advantage of my youth and interest in ancient Egyptian things just to sell me something, so my question to you is what lie has a salesman told you in order to get you to buy something, whether you bought it or not?

Can you condense the text into three sentences or less?
