I realize it's no guarantee (either way), but I'm always hesitant when I don't see at least ONE shot of a professional setup, massage table, dedicated room, please God oh God let there be a HEAD REST (that's a deal breaker), and SOMETHING that indicates there will be a professional massage.
Personally, a great massage, draped, and the guy can be in a hazmat (sp?) suit for all I care if it's a great massage and he's interested in making sure I have a great experience.
