Which legit shop is this? Usually your paying $60 for half hour at your traditional Thai massage shop, At Vitality I can get an hour $70 for an hour and get a rebate after.
As far as massage quality/type its probably in line with a sports massage Linda has unfucked my back and shoulders so many times, Polly and Nancy (before she left) give great Thai style massages as I mentioned earlier for a strong decent massage you need to see one of the younger ones whilst sacrificing a handjob.
This is the only shop I am comfortably tipping even after a legit massage cause its much cheaper.
