Typically the left side of an escalator dedicated to speedy individuals who
don'
t have the time or
patience to let the escalator take them where they need to
go, therefore, they angrily speed-hop (sometimes taking double steps) up or down the moving staircase and pass everyone on the
right side, leaving them with the following possible impressions:
"I'm more important than you; shove it"
"I'm wearing a suit and have places to be"
"Oh shit I'm late I'm late I'm late"
"I have to catch a bus, get out of my way or I'll trip you"
You can use this method to your advantage, but if you fall on your ass and
go tumbling down the moving stairs, you're on your own.
