Can't believe something this simple is so controversial.

IMHO everyone seems to agree that the seat should be relinquished, except for a that idiot harping on about male rights or what not. I have to agree that the OP needs to be more assertive in what she wants rather than fuming and saying nothing and fuming some more. The culture we're in requires a bit of assertiveness to get what you want . . . very unlike British culture.

I remember the crowded waiting rooms, but my wife was one of the pregnant women who had no problem asking for a seat, demanding reception provide another, or asking for some place to rest in the back. I think here you have to be resourceful or just accept it.
