I parked down by the waterfront on Saturday night. Didn't pay enough for parking. Came back to my car later that night, to find that someone had stuck their parking payment stub, good until 8am, on my windshield!

Thanks! Saved me from getting a ticket! PS, I paid it forward. Stuck it on someone else's windshield when I left, just as they were about to get a ticket. —Thanks the parking gods
