Yeah, that's always befuddled me, too. Why do people have to scratch off their tickets, etc, when there is a LINE. Buy the damn tickets and get the hell outta my way!
The ones who do that can easily be spotted sitting in their cars, with piles and piles of losing tickets littering the ground under their driver's window.
In theory, we are a "Classless" society, but I do not think this is the original meaning of the term.
