Gotta admit, folks like that help with the boredom. Up here, we just shoot 'em on sight.
I don't go to Walmart. Been there exactly twice in my life.
First time, bought a video surveillance cam which I could find now where else in town. Second time was when I (intended to) buy my first DSLR, a Canon Xt/ 350D. I'd checked their website, store locator, etc, and they were supposed to have 'em in stock
After going through about 4 people, you'd think nobody ever even HEARD of Canon cameras. I left in a huff, ordered online, and have never been back. I never will, either.
On the way out the store some "manager" asked something like "how was my shopping experience?" I told her that one person in the camera dept. had permanently lost them a customer in less than 5 minutes and walked out.
