The lady actually answered at least 5 calls during my 75mins session, which was indeed annoying. 

When the session finished and I was paying my bill, the reception lady (who I assumed was the owner?) “reminded” me pay my tips. Well, only if the massager was good please. When I said I didn’t have change, she said I saw your $50 in purse when you got your credit card. Wow, how sharp. 

So be prepared for the tip, cuz the lady know you have it :)
