Set up a couple's massage for a friend and myself....

Set up a couple's massage for a friend and myself. The waiting area and hot tub were nice albeit small. But in the massage the therapists asked my friend and me if there were any areas they should focus on, hers being her neck and traps area, mine being my lower back and legs. Halfway through the massage the therapists asked us both if the pressure was okay to which we both responded, "no much more pressure and specifically in the areas we discussed before the massage began." I am not sure why they asked us anything about our preferences because they did not pay any extra attention to our troubled areas nor did they increase the pressure when they were asked to. On top of all of it, I was forced to tip $50 for this unsatisfactory massage. I would not have tipped at all had it been up to me. And if you are forcing a tip, why not just make it part of the cost of the service instead of gratuity? The massage therapists did not deserve gratuity. I have much better service at an Asian parlor.
