This is interesting. The next time I write to Uncle Kermit, I'm going to tell him about your article. He's not really "into" the Internet, but I can describe what you've written here.
When it comes to beer, he's very particular.
His preferance is Miller Lite (He seldom deviates from this) and a requirement where there's no negotiating is that it must be cold.
At least once or twice when we've been out to eat, he has sent his beer back with the waiter when it turns out to be warm.
