Definitely the first time I've seen contagion kink. This seems like a good way to implement that, though. You don't normally think about planning food delivery around not washing your hands.
I think this is a cool idea, and the basic engine seems solid. The action queue worked well from what I've seen, and I liked the characters and the writing. If you want to keep working on this in the future, I could see it becoming something special. Plus, hey, your programmer art nails the vibe of the game.
I would have a bit of a wishlist for a theoretical future version - a visual indicator of the action queue, more distinct food icons, sound effects and music, etc. - but as a proof-of-concept thing for a game jam, it's a very solid effort.
