Major hotels usually add a 10% service charge to bills. Where it is not included a tip of between 5% to 10% of the bill would be appropriate if the service is satisfactory.
Airport porters expect for a small bag and for bags weighing more than 20 kg.
Tipping taxi and hire-car drivers is not mandatory, but if service has been satisfactory tip is sufficient for a taxi driver, Hire-car drivers would normally expect a larger tip.
