Fun, but hard

I cant get past level 28! I am doing everything right, but I fail, or wont get 3 stars on a level when I should. Ill get 2 or 1 star and Im on top of it, serve the food as soon as they walk in! And have it ready but no.. Fail. And this is level 28..

Game is really fun, but very hard.. And you dont get a lot of tips or cash to upgrade and make things faster which makes it harder.. I get it, but its to hard..
