This game has a great use of both the theme and the limitation!
I really like that the limitation of the game is ingrained into the gameplay and the concept itself, which is I think really unique! Losing hamburgers to cut off any waste by giving it to customers (during a movie intermission, if I get it right) is a very nice idea to have. Other than that, the issues I have to this game is already discussed much by the previous commenters so I have no need to tell them again. In conclusion, better mechanics and and gameplay could go a long way with this theme and gameplay basis.
