Disrespectful mother fuckers.
I never park anywhere that people can park on both sides of the car. It's also best to park on the passenger side of cars if you must park next to them. A car is always going to have a driver but not always passengers.
Unfortunately even this strategy isn't fool proof. Some douche still managed to put a quarter sized dent on the hatch and scuff my bumper in the rear.
No matter the time I never park close to a store, my condo, or the doors where I work. Lazy people who won't walk are are same people who dent car panels.
