Quark: I thought we'd have a toast to the memory of Chief O'Brien and Dr Bashir.
Jadzia: That's very thoughtful of you, Quark.
Quark: (seeing Kira's surprised) I can be thoughtful! (they all lift their glasses) To our dear, beloved comrades, we may have had our differences, but I'll say this for them - it's the highest tribute I can think of - they were good customers. They always paid their bar bills on time.
Kira: That's it?!
Quark: I'm not done yet. At times like this, I'm reminded of the 57th Rule of Acquisition: "Good customers are as rare as latinum. Treasure them."
