On a crowded train yesterday, hardly any seats. A woman (middle class), probably about 40 grabbed a seat and sat down with her daughter (assuming) about 7/8 on her lap. Next to them, a man about 75/80, standing. No offer to let him have the seat. A few stations on, the person next to them gets off and she plonks her DD down in the now empty seat. A few more stations on and they get off. The oldish man grabs the seats for him and his mate (similar age), so obviously he does want to sit down.
