Quote from Martin in Secret Admirer
Martin: Well, I don't get this, how could this happen? Niles: Well, the other gift was left in Frasier's squash bag, which is exactly like mine. And, I guess today the waitress must have mistaken Frasier for me. You don't suppose it's Daphne? Martin: Yeah, she took the second job washing that old Mrs. Lumpkin's hair just so she can give you Cartier.
