I booked a hotel in Phuket online, and I have paid all the taxes and service fees. Do I still have to tip?

Tipping is a foreign custom, which is different from taxes and service charges. A tip usually means that you give it to the bellboy or the aunt who cleans the room. If you give it to the bellboy, you usually pay after the bellboy takes your luggage to your room. When cleaning the room, you usually put the tip under the pillow.
