I always give up my seat to someone older than me or in poor health (and I'm 64!). My sons were always brought up to give up there seats, now 40, 37, 34 and 33, and my grandchildren have been brought up to do the same. I think its all about manners, and how your brought up. Unfortunately nowadays we are a diverse culture, and have different ideas on things? I think men in particular are not sure what to do nowadays, as a slightly different senario..but women are offended sometimes if a man open a door, or offers a seat...personally I cant get my head around it, but sign of the times?
