Phone: Do you have tickets for the show tonight at the Charlotte St. Art Centre?
Me: As of this moment we do. But the organizers sometimes pick up the tickets early on the day of the show, and the show's tonight.
Phone: Oh I know, but I don't have a ticket. Can I purchase a ticket?
Me: Well... if you can get here before the organizers pick up the tickets, then of course.
Phone: Oh... yes, I see... and you still have tickets?
Phone: Oh, good. So if I pay for the ticket by Mastercard my partner could...
Me: I'm afraid we can only take cash for tickets. We have to give the organizers the cash FOR the tickets when they pick them up... the day of the show.
Phone: Oh... yes... I see... well, then you're saying I would have to come in there and pick up the tickets?
Phone: And could I pay for them by debit, or does it have to be cash?
Me:... cash, yes.
Phone: And I would have to get there before the organizers pick up the tickets?
Phone: But you do have tickets left?
Me: ...as of this minute... yes....
