Airport Bus Express / unloaded my luggage without being asked
The driver unloaded my luggage in terminal 1 even though I didn't get off the bus since I'm getring off in terminal 2. Lucky I saw my luggage after the passengers going to terminal 1 so I got off the bus and called the driver attention that he just unloaded my luggage without my knowledge. I think this is a very serious mistake and could cause delay and inconvenience had I not seen my luggage. There has to be system in places so that this won't happen again as I frequently travel to Seoul from Singapore and ride the airport bus to ge to the city.
