What I smell with married men is trouble, frankly!
Ya got a nose for trouble, huh? :-)
If you get there early, you have your choice of the best spots.
If you wait too long, the pickin's are slim. You either have to lower your expectations and take a space farther away, or spend a good deal of time looking for that prime spot -- often waiting for the person who was there to leave.
I'm not sure how to fit infidelity into this theory. Is it taking a spot for which another has been patiently waiting, parking in a reserved section or tow-away zone, or simply rolling your SUV over the little sports car in the way.
Towanda!
