Correct. None of the semi legit spa operators pay any kind of wage to the girls. Imagine waiting from 10 in the morning till 10 at night, with a good chance you might only get 1 or 2 guests. In the majority of cases, a large part of earnings needs to go back to China to pay for mortgage and school fees (a lot of girls have young children back in China, whom they miss a lot). So subtract that and after paying for groceries, rent (even a little Toronto basement room the size of a closet runs at $600 - $1000 per month), phone and sometimes uber to work, there is not a lot left. So leaving a tip of $40 for a semi-legit massage with no extras is not that unreasonable. It is different if you go to a legit medical spa where massage specialists do get a normal hourly wage, in that case $20 would be appropriate. I don't mean to write a sob story, but just be kind, respectful and consider your tip is the girls only means of income.
