Could you propose ending the gift card/game component? It doesn't seem fair that you spend money &
put in the effort to cook. It's the gift cards that are throwing things out of whack. You should be able to partner up with someone who wants to pay $10 and have them give it to you for groceries! I think there's enough hooplah around the food, do you really need games and such too? My old office used to do potlucks frequently and frankly, they were a huge distraction. Fun, but still. The game component adds to the madness.
