My guess is that these clerks are really perpetual "students", who will be living with their parents until about age 35. After that they will be looking for some type of government handout, to help them get through the remainder of their years.
The liberal government schools and universities have helped them acquire their liberal snooty attitude, while making about $7.00 an hour. I take solace that the Borders employee parking lot is filled with 10 year old junkers, held together with Kerry/Edwards bumper stickers.
I buy at Amazon, but browse at Borders and love to mess with the freaky clerks. I like to make them squirm by asking for the conservative books that they never place on the front tables. Most conservatives that I know are really the type of people who "live and let live"....but the freaky clerks and their ilk are the most mean spirited, spiteful and hate filled group that I have come across.
That's why I still shop at big bookstores. I am a figure not to be trifled with - even in street clothes I'm kind of imposing to all but the largest lefty - and I can get VERY focused. Some find me VERY intimidating.
