Its not normal though is it ?
It does suggest a lack of control. He is not right in the head.
It is not normal and it would not be possible in most jobs.
But I do know a few people that hold it, I know a guy I used to go to church with that saw a woman he knew on the side of the road with a broken down car and he would not give her a ride because they would be alone in the car together. So he left her and called someone else to come get her.
In my job we often drive to meet with clients or to go to trade shows and often there is one man and one woman that are sent depending on the nature of the show.
