Elevator Etiquette

Here in the United States of America when the elevator doors open, and you are waiting to get on, you let the people that are on the elevator get off first. Apparently in Asia, when those elevator doors open it is full bloody riot time to get on the elevator. Kids, seniors, and physically disabled people be damned. Just push and shove to get in that box. I wanted to push back but they could have been ninjas and I was late for happy hour.
