The word gratuity is used to refer to a tip or a sum of money that is given by a client after a service. The gratuity is usually given to a worker who served the client. Gratuities are very common in the serve sector, especially in hotels to an extent that they are considered a norm rather than an exception (Johnson, 1997). However tips and the amount tipped is usually a matter of social customer and etiquette, which may vary from one country to another. While in some countries gratuities may be accepted as a form of acceptance of employee service, in other countries they may be perceived as bribes, hence disallowed (Holland, 2009).
