This is a very good question Sue. When I was training to be a reflexologist, Louise Keet always used to advise us to ask clients 'How can I meet your needs today?' Such a simple thing but so important that I have never forgetten it. You felt that your needs were not being met by your treatment, and that's a pity.
Going to a therapist for the first time is a bit like a blind date, don't you think? We have our expectations and that person may not live up to them. All therapists have styles that differ from one to the next, and of course different clients have differing tastes and expectations too. It's hard. As Melissa pointed out, there can be challenges to us therapists too. Rising to those challenges is what makes the difference between an OK therapist and a brilliant one I think I know a reflexologist who is recently qualified. She does some work with severely disabled people, and is finding all sorts of ways to make her treatments work for her clients. I take my hat off to her.
When I'm taking a history I use the time to try to get to know my new client and figure out how I can offer them the best treatment and an experience they will like and find beneficial. Sometimes they don't come again and you may never know why (hey, that's life!), but most of the time it works fine and you know from their response that you've done a good job for them. I try to remember to check whether they like music, although I've yet to find someone who asked for no music to be played. I check that the seating position is comfortable, that the person is warm enough, that the lighting is suitable and so on. I have no smellies at all in my treatment room as some smells can make people feel sick or give them headaches (I'm not good with people wearing strong perfume, myself). And then I give them what I think (and hope) is a great treatment!
Sorry if this is a little disjointed, but sometimes I have trouble getting all my thoughts to hang together in a nice and logical way! Yes, I have certainly had experiences like yours, and have come away thinking 'Yikes, don't make me go back there again!'. I've simply moved on and found another therapist who was able to 'meet my needs' better. That therapist you saw may have a booming clientele but may just not be the one for you. It's a funny old game, isn't it?
