Small accidents

I was dropping someone off at the airport. So on my way back to the trainstation, some guy with way too much luggage, stopped me to ask if this train is going to this direction. So I said "yes". He asked again, a bit rude. So once I again I told him yes and continued my way down on the automatic stairs. Almost down, I suddenly hear a lot of noise behind me. The moment I kinda want to look back to see what's going on, I felt what was going on. A suitcase had fallen down, bumped against my legs and swung me up, so I fell on the automatic stairs and smacked down again. Result: My arm needed stitches and I had a huge bruise on my ass, etc. Believe me, having stitches by the airport doctor isn't all that. Especially when you feel the first dread completely going through and burning you up. Still have a scarve there...
The guy was even so rude, to just go into the train. But he had to go out again. Of course police didn't do shit...
Why didn't the fucker just take the elevator (see more)
