Kam Lung Thai Massage - Bangkok, Thailand

I came for a massage on 6th April. The massage was OK but It was really off-putting to be told it would be 200THB as advertised outside, then when the massage started to be told that a 100THB tip had to be paid. When I whole group of Chinese tourists arrived the massage finished quickly around 10-15 minutes early.Very disappointing for my first massage in Bangkok.
