Would you use your Brown Bear Tag on a Wolvrine?

A few years ago I was on a Brown Bear Hunt on the Pennisula. We were hunting from a fishing boat and saw a Wolverine walking down the beach. Another fellow that was there wanted to get in the skiff and try to take it. He only had a Bear tag and wold have had to use it on the Wolverine. (In Alaska you can substitute animals of like tag value. The Wolverine was a bit cheaper so he could use it.)

The outfitter told him it was his choice but that he could not get another BB tag to replace it even though he had not shot one.

What would you have done?
