Yes. Yes. No. No.
There're really not too many circumstances, which can happen in life, which would faze me.
As a 13yo, saw a 9yo's skin partially ripped off his back when caught in an escalator at DJ's HO, in Sydney. It was one of the old type wooden ones'.
So anything after that was nearly a non-event.
I got caught in a S/C lift one time, followed Emerg. Procedures, as listed, & was out in two minutes'. I also had my mobile phone with me, but it wasn't needed.
So basically, both escalator travel, & lift riding, I enjoy.
