Your story is better than mine.
I used to work at Staples. I still hate the SMELL of that store. They use their own house brand of cleaner.
One day a fat, smell, poorly dressed moron walked into the store. Not rare. Hick country. Ugly, too. And surly. I got the privilege of taking care of this fine, upstanding scholar. He wanted a modem. You know, the thing you write e-mails on. He didn't have a computer. I wondered why he wished to have an add-on card without something to add it to. I explained to him the difference between a modem, which is installed in a computer, and a computer, which can connect to the internet if there is a modem installed. He called me a liar. This went on for thirty minutes. I wanted to make the sale as we get commission. He stormed out, much to the amusement of EVERYONE in that half of the store, which was approximately 100% of the people in the store. Judging by his appearance he would only have been able to afford it on credit. And he might have intelligent enough to buy a protection plan. I missed out on a big sale.
