I am of course just speculating (and I had a lot of waiting time to think about this), but there are a lot of people with a lot of luggage constantly going in and out. It makes the elevators be full faster (perhaps there is a weight based sensor to determine if the elevator is full, and the luggage tricks the system into thinking the elevator is not full yet, because a piece of luggage is lighter than a person but sometimes takes up more floor space than a person). Furthermore, people with luggage take longer to get in and out.
It's a tower in Kuala Lumpur btw. Since it is rather hot here and the elevators are not airconditioned, it's extra uncomfortable.
