Quote from Roz in Here's Looking at You
Roz: Hey, you wanna hear my pet peeve? You're in a department store, and the clerk is right in the middle of helping you and the phone rings. So he starts taking care of them. And you're left standing there going, "Excuse me, but all I did was come all the way down here in person, while some joker is sitting at home in his underwear getting first-rate service." Don't you hate that?
Frasier: Well, actually, I do most of my shopping by phone.
