A few years back, my father backed out of his garage and sideswiped my car- he just forgot my car was there, and did everything as he normally did. My mother started in saying that he shouldn't be driving any longer, but I thought it was the sort of mistake any of us could have made...it was a very tight driveway, and another inch over and he'd've been fine. Fortunately, though, he sold his car a year or so later.
As for the employee discount- back in the 1950s, my father worked for a packing house that also manufactured sporting goods (think of Cast Away's volleyball). The employees were allowed to buy all they wanted of the company's goods, for the use of their family, at big discounts. The policy was rescinded after sales dropped dramatically in a particular neighborhood, and the company discovered that several employees who lived there were purchasing enough meat to feed dozens, and enough sporting goods to equip several ball teams. They were buying wholesale and selling to their neighbors at a discount, and doing enough business that the neighborhood stores were hurting.
