when you look back at the original post about wearing hoodies or hats, it refers to wearing the head dress while at a restaurant attached to a pub. Okay, maybe not a real formal restaurant requiring a formal dress code, but wearing hoodie (pulled up on your head) or hats is a different matter to wearing them at the pub or other social function. When it is cold a hoodie is a great thing to wear, but the wearing of the hood on your head I feel is a time and place thing, not a given wear it all the time thing.
I agree manners and respect, are not restricted to one generation, a bit like the hand out mentality. At times people seem to be out for there for one person, them self, and everyone else is expected to wait on them. Some people however have turned this into a real art form at times.
