I thought it funny that Gold pressed Latinum was effectively worthless if the Latinum was removed, gold being a relatively inexpensive commodity.
No, I think the one I was thinking of had someone trying to pay him for giving them medical attention. He said, as a Starfleet office (or something), he couldn’t accept. He did tell them where they could use their currency though.
As I recall, latinum was pure fiat money anyway. Its virtue was that it could not be replicated; and it was always used in liquid form, the gold being used as a container (and perhaps to provide heft and beauty).
