Thing is, what right do people have to fiddle with your car in the first place? I don't want anyone playing with my windscreen wipers, even if they are just placing flyers. Car Guards are there to protect your vehicle and should rightly stop anyone from interfering with it. Sure, hand flyers out - but don't screw with our cars.

Having said that, it does sound as though those bouncers went a bit overboard. Maybe they were trying to ensure you didn't return.
