No, follow the "when in Rome do as the Romans do" rule is the best.
Taxis - the local practice is to round up to the nearest dollar. Fare = HK$31.50, pay HK$32. No need to tip extra as in the U.S. Limo driver who picks you up at the airport and helps with the bags, I'd tip him/her HK$20.
Hotel - I generally tip HK$8~10/bag.
Restaurants with the 10% service charge, I just leave the loose change, about another 1~2%. Those without the 10% S/C, I leave 10~11%. Those local eateries where they give you the bill to pay at the cashier on the way out, no need to tip. No need to leave any $ on the table.
