I also think some of it has to do with the other people who are working at the time (supervision). and the location of the room. I notice when I am placed further away and dim the lights as low as possible when i get in the room, it allows for better action. Again, i also think that saying the word 'yes' as it gets closer is important because the last thing they ever want is to be accused of something that wasnt solicited. I have seen Shawn four times , the last two times I was very happy with the experience.
