“Who is the idiot who decided to put a wheelchair on an escalator? Everyone I’ve seen has a sign for no wheelchairs and no strollers.”
Exactly my thoughts. I thought they were specifically verboten on escalators. How can one even imagine that could work? Sure, if there is an attendant leaning the chair back, but even then, the steps don’t seem like they would be wide enough for the big rear wheels.
Well on 2nd read, if they hired a gate-to-gate attendant they are distinctly liable.
