Just thought I would share an experience I had with incompetence this week.
Place: Macca's drive through
While waiting in the drive through after paying I didn't quite clear the "order here" window due to the line up infront of me. This lady in a silver Commondore decides to creep up to see if she can reach the window. Not looking where she's going hits the back of my car. It was a gentle tap and I know she hit the tow ball with her number plate. So eager to place her order and pay for her purchase she stretches out of her car window to reach the macca's window she must have slipped of the brake pedal and hit my car again. This time I get out and she grins and gives me the thumbs up.

:
No damage done to my car the ball took the impact and there is a nice imprint in her personal plate and bumper.
All she had to do was wait 10seconds and she would have had all the room she wanted.
