If waiter repeats customer´s order, he is more likely to get a tip. Just by repeating order, 78% gave tip compared to 52% when waiter just confirmed the order. It is a simple thing, but how many waiters really do it? It is also good rule to live by every time you are serving customers. You need empathy but you need to deliver as well.
Show that you care
People love their own words and decisions. Repeating the order confirms that you have done the right decision. Customers will experience sameness with the servers, like them more and will leave bigger tips.
Don´t screw up
When waiter repeats the order, there are higher likelihood that the order will be right. By doing something that showcases interest of your customer´s needs, you are also securing your own back.
It is win-win situation: you appreciate the customer and same time you minimize your probability of doing mistake. In Singapore context though, I don´t know what would be the result on tip when waiter repeats your order but is still able to mess it up.
