Frasier: It's kinda busy, any chance of getting a table?
Niles: Not at the moment. The table by the window received their check five minutes ago but they've been just sitting there, yammering away ever since. I've been shooting them dirty looks, but they haven't budged.
Frasier: Show me the look. [Niles gives a stern expression with a raised eyebrow] They're there for a while.
