OK, yes, I screwed up.

I combined in my head the rules for offering Loot to NPCs with the rules for trading Loot for shticks. You can't trade Loot to NPCs if it is also drooled over by another player, but you CAN trade it for shticks. I think we had it that way in a previous version of the rules, and then dropped it at the last minute because it hurt Elan and Durkon (the primary users of the loot-for-shticks rule) too much.

I'll change my previous answer.
