For the last couple of years, the issue of whether tips should be kept by the server or the restaurant has been hotly debated. 

Many customers who leave a tip assume, rather naively nowadays, that the server gets to pocket it all. In fact, many organisations instead use tips as a way to boost their profit levels. 

Many companies voluntarily changed their policy on keeping tips following a lot of bad press (for example, Pizza Express) but now it seems that the practice will become unlawful in any event. The Prime Minister announced the new plans on 1 October 2018 in a bid to end exploitative employment practices. We therefore wait to see further developments in this area.
