Tipping is a voluntary additional payment made for services ( America for example ) tips are comidered to be compulory given that workers such as waiters .Hairdressers and staff dont have very hight wages.

In Britain tipping is more of a choice , depending on the kind therestand you are in and the quality of the service you recive.

In my opinion , in a normal , case yo need to pay 10% , but it the service is very good , I pay 20% but it the service realy bad I mont likely , I dont tip toothe service .

Another case in Chile most of the people give the change ,that they recive , an a tip .
