This is in response to Linh who did not have a good experience with the lady that worked on her. Yes sometimes, maybe 10% of the time, you'll get a dud. I have too. But most of them are excellent and really know their business. They will find your trouble spots without your even telling them and oh boy does that make it worthwhile! Try again and ask for tony or one of the other males that work there. They have all been good for me.
