Dorothy Sayers vs. Teetotallers

It's funny how authors sometimes put their opinions in the mouths of their characters, where they can't get in as much trouble for them. My wife and I are reading Dorothy Sayers' Strong Poison. Dorothy Sayers, who was a big fan of a little drinky-drinky, has her detective, Lord Peter Wimsey, say this of a jury foreman:

"I'm convinced that that foreman is a teetotaller--I saw ginger-beer going into the jury room, and I only hope it explodes and blows his inside through the top of his skull."
