When I was there for a 4 day class this year, there were no real sales effort. Each day at lunch time they had some soft sell presentation you could sit and listen to, or not. One was for ear protection, one was for safes, and one day they spent maybe 15 minutes talking about how beneficial having a membership could be, comiing over and over etc. But, they weren't selling directly and suggested to the group that others in the group might have memberships available. In fact there were some women in my class that wanted to buy memberships but could not buy them from the school.....
Again, you weren't required to go, sit, or listen. Just something going on at lunch.
Knowing how the email marketing is, I was concerned I might run into hard-sell tactics while I was there. But, it just didn't happen.
