Rude driver

Wanna complain about this bus driver (Sadly I did not note down the bus number). So today I was gonna board the bus and the doors closed on me and so I knocked on the door. And guess what happened. The driver looked at me, turned away and continue driving. WTH!!!! Super pissed la! What am I? Transparent ar? Am I wearing an invisible cloak that the driver cannot see me? I don't know what is his problem, but it annoyed me to the max that he has completely not acknowledged my presence!
