Ferengi Rule Of Acquisition #285: No good deed ever goes unpunished.
Quark: You want something from me, don't you?
Kira: How'd you guess?
Odo: It's simple. We've been here more than a minute and we haven't insulted him, threatened him, or arrested him.
Quark: Exactly! So what is it, and how much trouble is it going to cost me?
Odo: (Kubus, a Cardassian collaborator, arrives on the station creating a stir among the Bajorans) What's going on here.
Eblan: See for yourself.
Odo: Secretary Kubus. Last I heard, you were living on Cardassia.
Kubus: I decided it was time to come home.
Odo: Welcome back. You're under arrest.
Kira: We just need you to bypass a security seal.
Quark: Isn't that... illegal?
Odo: Spare us.
Kira: We need access to certain communication files in the Vedek Assembly records.
Quark: Perfect. Not only is it illegal... it's sacrilegious.
Kira: I'm sure the Prophets won't mind, just this once.
Kira: Now that I know that you're here, I'll be sure to inform Constable Odo to increase station security.
Winn: That won't be necessary. I feel quite safe here.
Kira: It wasn't your safety that concerned me.
Quark: Whatever she told you, I didn't do it.
Odo: Relax, Quark. No one's accusing you of anything.
Quark: The day's still young.
