When your credit-card receipt is presented to be signed, the tip space should be blank—just draw a line through it—or you could end up paying a 30% service charge. Most taxi drivers don't expect a tip. Tip massage therapists at spas or hotels 10%; additional gratuity for services you arrange to your hotel or villa are at your discretion, but always appreciated.
