It's a fun idea based on a nice wordplay!
I did notice however that the guest that were seated seemingly weren't despawning I think...? This led to me seeing a lot of happy customers, but no wishes from new customers...
I also sometimes had to feed a customer the same food twice. In case it was intentional, I think it would be nice to see some indication that the game aknowldged the first food and you need to give the food again, because right now it felt a bit like a bug.
