I think in part people are more impatient now and in a hurry, and give scant regard in some cases to other people around them. I drive buses in an area which has had a huge influx of Eastern Europeans, and they don't seem to understand the queuing system which leads to problems at times. The Polish do and are generally polite. But equally some English people are damn rude also. The worst offences are not letting people off the bus before they pile on, and my pet hate, talking on the phone and just putting money down (I am not Psychic) and getting annoyed when I ask them to talk to me not the phone.
Our elderly neighbour wanted to see the stage show Only Fools and Horses at the Haymarket in London. So OH went with her on Wednesday, elderly person with dodgy hip and the underground was a bit tricky as she found, so it was taxi back to station. But some people behind just kept talking through the show, so everyone around was having to keep telling them to be quiet. They were old enough to know better, they were also the noisy sweet rustlers also
