Well. Congratulation. You have managed to make probably the worst grind game's I've seen in the 5 years I've been on this site. This "game" is basically a VN as you have absolutely no influence on the progress.
* The number of waitresses are set in stone. Even when you have a service rate below 70%, you can't hire additional waitresses.
