A question for you. You are getting onto a coach to go somewhere long distance. As you climb the steps, you see the driver is a guy with long hair and stubble, wearing a Motorhead tee shirt and a baseball cap on backwards. He has visible tatoos and is chewing something.
Or, as you climb the steps, you see the driver is clean-shaven, with a neat, conservative haircut. He is wearing a clean pressed shirt and a tie and greets you politely as you get on.
Which driver would you feel most confident about?
The first one of course. With the second one i would immediately ask myself if someone has kidnapped the bus and is planning something nefarious. But that could be just my perspective as someone who uses public transport in Berlin every day.
