I'm the same with my cars.
I have a spot that I always use. It's next to the pillar (so I only have to worry about bad parkers on one side), far away from the shop entrance (so that the people who drive around for ages looking for a spot near the door don't park near me) and near the entrance ticket machine thingy (so that no-one thinks of smashing my window because there is always an audience). I always feel a little sad on the occasions that my spot is taken...
i have a spot too ><;; it's near a curb island thing, also a good hike away from the shop, I park up as close to the curb as I can because then i figure if someone does park near me (and assuming they stay in the white lines) they have heaps of door swinging space and there should be no reason as to why their door would even connect with mine.
Glad there is someone else out there!
