I started with the department stores like Zellers and Wal-Mart. Nothing there, so I started going to computer and electronics stores. My first stop was The Source by Circuit City (which used to be Radio Shack.) I looked around at the computer peripherals, and a store employee asked if I needed help.
"Do you have any trackballs?" I asked.
"What's a trackball?" was his response.
Dude, you work in a computer/electronics store and don't know what a trackball is? "A computer pointing device that is not a mouse," I replied.
He snorted. "There is no such thing as a computer pointing device that is not a mouse," he informed me.
"Oh yes there is," I replied. "I've seen them. I've used them."
He finally agreed to look them up on his store computer. "Oh, so that's what a trackball is," he said when he finally found one. "But we don't sell them. They're too expensive. None of our customers would buy one."
