Good on you
You do have an advantage of being big (stop giggling ta the back!!)
but pointing it out to someone like that might just stop them doing it again in the future when a little old lady is trying to push her disabled husband in
and sending the images to all and sundry is also good - makes the employer consider more extensive "training"
Sorry - addendum
things like this remind me of something from many years ago
my Dad was disabled - fractured spine when a bomb dropped out of a Stirling he was bombing up during WW2
very low down or I wouldn;t exists - but he could only walk with leg irons and a stick
anyway - when I was old enough he waited one Saturday until my Mum was out and then asked me if I would help him get to a shop in Chester
He had it all planned out
There was disabled parking nearby - Chester was a problem for it all those years ago - and the shop was within range
It was the first time in most of his married life that he would be able to get her Christmas present himself!
so we went down to Chester and
all the disabled parking was taken
I have always suspected that most of them were not disabled drivers
so we drove home and he rang my Mum's sister and asked her to get the present - as usual
only a little thing a long time ago
but it showed me how important disabled parking is
even my ex realised I would not give way on that topic and it was one of the few "rules" of mine that she never demanded I transgress
(she did ask several times)
