LOL, please do tell you guys xD. I haven't had anything quites as bad as most of the stuff on there...but the worst one was this:
I work in a locally-owned RadioShack. One day a lady comes in and wants to buy a mouse, so I walk her over to where we have computer supplies and show her the mice we have in stock. She keeps saying she wants one that "lights up." So I figured she wanted an optical one because they "light up." She kept saying no, and I finally figured out that she wanted one specifically that lit up on the outside (had clear plastic so you can see the LED's light up on the inside). Needless to say she didn't buy one from us. So anyway, I walk back behind the counter as she walks up to the coutner as well to look t hrough one of our fliers. I stand idly behind the counter, making myself "available" in case she had anymore questions. She speaks up and says, "what's this?" as she points to a GPS unit. So I go, "oh that's a GPS unit," and before I could say anything else she says this: "Oh you mean its one of those things that can drive your car for you?" I was literally in shock. I had a massive urge to say "yeah! you wanna go try one out!"
