Got the train home today from London at rush hour. It was packed, not a spare seat to be had. At the front of the train there are always a few unreserved seats, including 3 sets of priority seating and 2 tables. I sat in a priority seat. Of the other priority seats, 3 were taken by men with a further 7 men in the table seats.
Obviously pregnant lady (with a baby on board badge for extra measure) got on and stood in the aisle as it was so packed. I looked around expecting someone i.e. a man to offer their seat but no one did. I stood up and she took my seat.
Now, obviously there's a slim chance that the other people in the priority seating had non-visible seating needs but it's unlikely they all did. Am I showing my age or is it no longer the done thing to offer a seat to the elderly/pregnant ladies etc?
Incidentally, when I stood in the aisle a man sat at the table offered me his seat 
. So he didn't feel like he should offer it to a heavily pregnant lady but he did to a an obviously non pregnant lady?
