go up the down escalator and down the up

I was 18 and working in a department store. Well, early in the morning, we’d open our stations for the day and then get bored, waiting for the store to open. There were a lot of young people and that was one of the ways we amused ourselves … we’d have escalator races up and down. Definitely go up the down escalator and down the up escalator at least once in your life. And try to come in through the out door and out through the in door.
