Tipping is common practice in South Africa for a range of services. In restaurants the accepted standard is around 10% of the bill, although sometimes a gratuity will be included (often in the case of a large party). It is also appropriate to tip taxi drivers, tour guides and even hairdressers. If you park a car in a populated area such as near a shopping centre, street security guards will usually ask whether they can watch over your car and in return should be paid a small fee – anything from two rands upwards.
