I expect same news provider will now provide a headline story, "male, middle aged man deeply offended when sternly rebuffed after offering seat to woman with small child"
I'm happy to be considered out of touch, old fashioned and will insist on doing nothing more than smiling if anyone told me to f*** off as I offered them my seat. I was brought up to show some manners and if I think there is someone of any age or gender that I may perceive as be more needing of my seat than me, then I'll make the offer. No is absolutely fine as an answer.
May be I ask differently or just travel different places to everyone else but I've been offering seats to people all my life and I can honestly say that I've never even come close to being told to f*** off as a result.
