I'm weird about being touched. I don't like strangers touching me at all. When my ex and I got married, I sucked it up and agreed to get a couple's massage at some place up in Sedona. Bad idea. I already have lower back problems. I have since my oldest son was worn. I warned her and asked her to be gentle, but in the end, I was in tears and told her to stop. I hurt for days. Years later, I worked for a dentist who wanted to treat us all, so he set us up with pampering packages at a country club in Scottsdale. We all showed up to work one day and they had a limo waiting for us. The gesture was really nice- beyond anything I ever received from an employer, and I couldn't reject it, but I tell ya, I would have rather spent the day at work.
So, no, I've never done Massage Envy. I know people who do and are super happy with it. Hearing about a bad experience with a massage therapist from there is pretty rare, and it usually comes down to the person preferring a specific type of massage that wasn't the therapist's specialty. For example, the person wanted deep tissue, and the therapist gave better relaxing massages. None of that was ever a problem for the people I knew. They'd just request a different massage therapist on the next round or find someone they liked and go with it.
