Pet peeve

This had been bothering me a while now. Why do people with no luggage or trolleys or strollers swarm elevators especially when there are escalators nearby.....??? And then they don't know elevator etiquette. Erm.....if someone is trying to get out,you should move. And if you are going into the elevator, wait for people to get out.....that way,there would be more room for you to get in......And if someone says "excuse me" or "tumpang lalu" it really just means that you are in their path and it would be logical to just budge :-/
