Had that happen back in the early 90's in Harrisburg PA in a hotel parking lot. Just one of those "what the h*ll?" moments in life. Report it to the police if nothing else, and like Snoopy said its an opportunity for new wipers.
I bought 'again' original wiper from dealer (27$/each) and found later, at Walmart, Ultimate X wipers at 18$/each. They look very similar to originals at works great. By the way, HHR use 18'' wipers for windshield.
