Same city, same problems... The best way to protect your car in a garage is to tip the attendant(s) regularly

So it's almost $50 per month plus... And some garage attendants wash the cars also... ($20 each wash) Ask them, if available, use this "private" service once in a while too.
Talk to them... You should know their names, hobbies, and the football teams if possible... If you keep that up, in two months your car will be as shiny as their boss' car. No-mo touch-up would be needed...
Hey, cursing up and down on your walk home is still free....
Long live black plastic bumpers...
