they are talking about boons that effect the entire party. When you champ orders a drink with Garth it only effects them, but if you eat the Bento or drink the Pale Ale the whole party gets the buff. It's considerably stronger that way
Then their price would likely need to be jacked up so it is in line with the existing team-wide boons. So ideally the new versions of those boons will exist in a separate menu of Garth's interactions, something like "Buy everyone a round".
