I knew another therapist who tried to put people to sleep so she wouldn't have to work as hard. (They call this kind of relaxation massage a "fluff and buff.") The most dreaded customer is the one whose body is hard as a rock and totally resistant to massage....and they keep telling the therapist to use more pressure. "I broke myself on one guy, and I swore never to do that again," she said.
The best massage is based on communication between the therapist and the client. Talk about what's going on with your body and what you need before the massage, and give them feedback during it. But it's also good to know when to be still, and just experience what's happening in the moment.
