Well you kind of have to deal with large amounts of people with blanket statements and blanket policies that kind of 'in lue of any other idea, go with this..."
And, these are not the Denny's of New York, so when people are out paying $80-100 each for dinner, then different rules are in effect I think, in the same way that when I work the Symphony I not only dress a lot nicer than I do for a rock concert, but I really watch my language too. Different crowds, different settings, different ground rules. So where I can use the "F" word pretty much as every other word in a sentence for a band, I try to remember I'm in a different place with the symphony where, as it turns out, 'piano' is not the only obscene word in the language anymore.
So I would expect a different level of manners, and a classical sense of manners at that.
