my 2 cents worth
As someone who is NEVER intentionally rude to CC ( I need you to nurse me through as a nervous passenger!), I'd just like to add my 2 cents worth.
You mention that you great each passenger personally , I don't know how you address peopl but personally I loathe being addressed by my first name by someone who doesn't know me.
Possibly a cultural thing , and I realise that you haven't said in what manner you address people , but it would make me cringe ( not rudely, you understand!)
