Where'd my bus driver go??

Yesterday, I got on my bus to go home after work and I was surprised to see that I was the only person on my bus! I thought, "Hey, this is great! I can sit wherever I want today!" So, I sat down and began to look at some papers from school. After about a minute or so, I looked up to see why we hadn't moved yet, and the bus driver was gone! I stood up to look outside and saw him going into a hair salon! What bus driver leaves his bus running with someone in it and goes into a hair salon?! Not to mention, we were on a hill... if something happened, I would have rolled down the hill in a bus with no driver! Hey, gotta love Korea!
