so if u park ur car at Target and a guy pushes a shopping cart in to your car and leaves a nice dent and flees, ur gunna go to the Target manager and ask for him to pay for it? its driver courtesy if you ding someones car to leave a note, but if their an ass and they just bone out then your just screwed... person who owns the parking lot has no liability, the person who did the damage is liable, if you dunno who did it then you've ur just screwed.
