Just back from HCMC. Have gone to foot massage for 3 times. it cost 100000vn for 1 hr. I gave 30000vn for the tips. The guy who did the massage seems very unhappy. As their english is not so good, they seems told us that the tips should be the same as the massage cost. I just wonder.... Please just give me an idea so when i go to HCMC next time, i will know what to do. thanks.
