Here we go again just greedy for money.Why would you have to buy extra customers? That's like begging for custom it does not happen in real restaurants so why in simulation games.When you reach the end of a level you get a notification saying not enough customers.So you have to pay for gems just to get you to the next level.If you don't buy any gems your stuck.Also the items you need to buy just get more and more expensive and again you have to pay.UNINSTALLING I DO NOT RECOMMEND THIS GAME
