We spoke to two etiquette experts, who suggested leaving a 15% to 20% tip, if you're able. Twenty percent is generous for the massage therapist and easy on the brain, which may be feeling more relaxed than ever after a massage. The math is straightforward.

During this type of therapy, you can expect to be massaged across many problem areas in the body. These problem areas can include the neck, back, shoulders, legs and feet, where tension can often reside. In addition to these areas, you may also receive massage therapy for the head and arms.

You'll be happy to know that you can head to your massage fully clothed. If you opt for this route, consider the clothes you want to wear and what might or might not work. It's best to leave heavy fabrics, such as denim or wool, at home and choose lighter clothes that are thin and form-fitting.
