Here's a funny story (sort of). we wrote "no sales pitch" on our treatment receipt or whatever we signed before we had the couples massage. At the end of the massage, we were asked "why did you write that?" So we explained, that we weren't interested in a sales pitch on products, that my wife would probably buy something anyway, but she'd ask about what she was interested in, and that we'd read on a discussion board that if one didn't want to have an automatic sales pitch at the end of a spa treatment, that if we wrote that, then there wouldn't be one. The two massage therapists told us that it had been happening more and more often....and they finally decided to ask someone. (Or did they ask everyone who wrote it as a way of trying to work into a sales pitch? He asks cyncially) Anyway, they then told us that they only tried to offer products they sincerely thought one or both of us could use, toxin removal, etc., etc. and were we interested in hearing about them. My dear wife of course agreed to listen...but we didn't buy anything as we'd just been in Orlando at a hotel with a great spa where we do buy products we can't find at home.
So even writing "no sales pitch" - well, you might get something.
