Do I need to tip in restaurants and hotels when traveling to Hong Kong and Macao (free travel)? How much do you usually give?

Hello! If you travel to Singapore, you generally don't need to tip. Hotel and restaurant bills include 10% service charge. In other places, if you think the service is good, you can give a tip to express your gratitude! If you sign up for tour groups, tour guides and driver services, you usually have to pay a tip.

thank you
