I agree with many of the responses from squints - 2008?
Good snobbery isn't flatly cruel. It's considered gauche in rarified circles. The goal is to put a lesser status person in their place without the appearance of having put much thought or care into it. If you lean too far into the insult you risk losing more face or prestige than the person you've insulted. Noble insults are best wrapped in the clothing of a compliment.
Examples: These usually require a slow up-and-down appraisal, the glance of snobbery.
"I'm glad to see you've done so well for yourself."
"You must find many relics in your journeys."
"What a unique gown."
"The gods bless a simple man."
"It must be a great a relief to be unconcerned with courtly life."
"It must be a thrilling life - to survive by your wits rather than your reputation"
"I admire your perseverance."
"I fear you will find our company quite boring. Nothing but chit-chat about politics and money."
If they refuse to bow or show deference to royalty, the monarch never shows offense. Others show it for them. They instead are cool and cutting. How'd they'd handle it:
"My faithful subject's wounds obviously trouble him."
"Now now. None of my dogs know how to bow either, but we know they are faithful."
"Our friend is unfamiliar with our customs."
"The horrors you must have endured to forget the kindnesses of civilization."
"You remind me of my brother, may he rest in peace."
"Ah, a revolutionary. Please leave your pamphlet with my footman."
