I had a driver do something stoopid once and I got a complaint from someone who saw it. When the driver returned, I asked him about it and he looked at me with this dumb expression on his face and said "How did they know who to call?" I looked at him in total disbelief and said "You're driving a truck with your employers name and phone number on it, not on one side, but three. How do you think they knew who to call?" He didn't last much after that.
