Tipping isn't considered essential in Hong Kong as many hotels in Wan Chai Hong Kong the likes of Cosmo Hotel Wan Chai Hong Kong impose a service charge on top of their usual bill, which is made transparent to the customers from the beginning. However, if you really need to reward the staff for exceptionally good service, you can proceed. But most of the time, you may find waiters chasing you down the street to return the balance. Taxi drivers in Hong Kong, too, don't expect to be tipped. Nevertheless, if the fare comes up at an odd number, round it up to the nearest dollar and pay.
