We all thank the bus driver here, too! However, I do think people are not as polite as they once were. I have had doors let go in my face, people barging into me, and stood like a lemon holding a door for someone who swept past without a glance. I might add I even stepped off the pavement for the local vicar, as I was walking my dog and he was laden with shopping bags and, standing in the gutter as I was, he swept past without a glance. I have actually called after a person 'Think nothing of it - oh, clearly you don't!' when I held a shop door back for them, but that sailed straight over their head as well. Obviously far too important a person, and probably just saw me as a doorstop.
