I must admit I was frustrated today by finding people coming to a stop and blocking every escalator and travelator I went on.

As far as I'm concerned, they're to speed you along, not save you from unwanted exercise. These people seemed totally oblivious.

Why can't they just stand to one side? Or am I just a grumpy impatient old git?
I do have a chronic ankle condition that hurts when I walk but I hate standing still.

What do you prefer? Stand or walk/climb?
