Has anyone else been accosted by these cleaners who try to clean your windscreen while you are stopped at traffic lights? I find it most annoying. I had to scream at the guy to stop and he still tried to continue. Eventually I had to get out of my car,square up to him to get him to leave my car alone. Are these guys allowed to do this? I have no problem with someone trying to make a bit of cash but what I find particulary rude is that they still try to continue even after I have told them that I dont want the service and to get away from my car. Any advice on how to deal with this annoynce?
