Hey good plan - if we can't ban him then let's patronise him to death!

Hey, if the shoe fits.

Reminds me of an old "Cheers" episode. Couldn't find the exact text on the 'net, but as I recall, the exchange went something like this:

Sam (to departing customer): Thank you for patronizing me.

Frasier: Sam, I know you were trying to use a big word there, but I think what you meant was, "thank you for your patronage". See, 'patronage' means they're your customer. 'Patronizing' is the way you might speak to a small, dull child.

Sam: You mean, like right now?

Frasier: Aren't you a clever boy.
