I don't think anyone should be discriminated against solely because of their appearance but surely there are reasons for "weight in proportion to height?"
I wouldn't want to be smacking passengers with my caboose every time I walk up and down an aisle or taking up half the galley when it's small enough already! I don't mean that in an offensive way but surely if you work in such a cramped space as we do, you have to take size into consideration?
Waiting for the backlash now...
