Ettiquete on public transport

When I was a child it was considered good manners for a child to stand up if an adult wanted a seat on the bus. People also moved their hats, bags etc if they saw a passenger who needed a seat. Now I see young children occupying a seat. People who will not move their things or move up to allow people to sit down-. I find it is the mature people who have the least manners. I had to ask a woman in her 50s to move her bag so I could sit down. She then spoke on her phone about sitting "next to an idiot". She stood up to get off the bus but did not say excuse me . I said I was getting off at the next stop and as suggested by the signs on the bus - it was best to sit down till the bus stopped. When we got off, she walked a few yards and turned round and told me that I needed to have manners. I personally thought it was the other way around

so my question to the grans generation - do you encourage your grandkids to stand up or sit on your lap? do you move your bag or hat to allow people to sit down?

or am i living in the wrong era?
