My rule of thump is only to give up my seat for the benefit of disabled people, elderly people, pregnant women, or children; therefore, I have the same expectations of others. If a guy offers to give me his seat for no apparent reason, then I would have and done so in the past politely declined the seat to avert any advance attempts. Perhaps, this can be viewed as overeating, but I prefer to have limited contacts with strangers, and I feel that by accepting the seat one’s obligated to extend or acknowledge attentions from that person.Originally Posted by Southern Crane
