One of the reasons I moved from London was that I was getting fed up with people, particularly younger people being so rude. I know this sounds old fartish, but it never used to be . . . . . blah blah etc.
I go to France quite frequently, and with the exception of Paris, people of all ages are just so polite and courteous. It really is not unusual for youngsters to nod and bid Bon Jour for no reason whatsoever, they don't know us. It's about respect. The French still have strong family bonds and traditions like eating together etc. Sunday everything is closed, it's a family day not another shopping day. We're losing all this, sorry, we have lost all this.
I do business with French people, wine business
Emails are always Dear M

Responding on forums is similar, it's about respect.
