A new café in Wiesbaden is charging customers for the amount of time they spend there, not for what they order. Apparently it works in Russia. I don't know how well this would go over in Paris where lingering over a café crème and watching the world go by is considered one of the city's great pleasures. I like to keep on the move and am not inclined to sit for hours over a cup of coffee. even in Europe, so this practice wouldn't affect me.
