1.I think how munch tips you would pay depend on the food and services in the restaurant.
我猜你想说的是：我认为你应该按照餐馆提供的食物与服务来给小费.
改错：1.In my opinion,the amount of tips you pay in a restaurant should be based on the food and service provided.
2.If you are pleased with the food and services in the restaurant,but you haven't enough money,you may pay low wages to encourage the service people to work better .
我猜你想说的是：假如你对餐馆的食物和服务感到满意,但却没有足够的现金,那么你可以透过付低工资来鼓励服务人员更努力工作.
改错：2.If you don't have enough money but still satisfy with the food and service provided,you can encourage the service people to work better by paying them low wages.
3.Of course,you also can leave a little tip or spend more money on services.It can show pleased the customers is with the service in the restaurant.
我猜你想说的是：当然,你也可以决定要在小费及服务上花多或花少.这可以显现出顾客对餐馆的服务及食物感到满意.
改错：3.Of course,you can decide how much to spend on the service.It would show how pleased the customers are with the service provided.
[custermers是副词,用are]
第二和第三句语法和逻辑上不通.我多管闲事的按照你列出来的要求写过了一篇：
In my opinion,the amount of tips you pay in a restaurant should be based on the food and service provided.Paying tips is actually meaning that to spend more money on the service provided.By paying some reasonable tips,you would encourage the service people who only get low wages to work better.From another point of view,tips amount can also show how pleased the customers are with the service proveded by a restaurant.
