Around this time of the year, with parking lots at local shopping draws close to full, it can be great fun playing with the people trying to snipe a spot.
Especially the obnoxious and annoying drivers who block other cars from turning, mess up the already slow flow of traffic, or who are only half paying attention while they have a cell phone sandwiched between their ear and shoulder, with their head half cocked.
Say there's someone obviously waiting, or even better, slowly driving down a lane of parking, sort of watching people walking to and from, to see who is going to get into a car and pull out and free up a prime spot. You can play with these people by making simple eye contact and kind of throwing your head as if to say, over here. Then you walk between two cars in the row of cars, moving to the next lane. And of course slowly or purposely losing the ignoramus who fell for your signals.
Note that I only do this when the people are oblivious (purposely or otherwise) to the open parking spots a hundred yards away, at the end of the lot or, where, god forbid, Mr. or Ms. Sniper will have to walk an extra 200 yards.
It's especially satisfying to do this to the self important looking jerks. Middle aged women driving Range Rovers, who look like they just had cosmetic surgery, or middle aged males, who look like lawyers, driving black Mercedes, and especially when they give the impression I'm too busy or too important, to walk from the back of the parking lot, so I'll just block traffic while I wait for someone to pull out.
