Honestly, Ceroc does pretty much all it can do to retain new members - from a purely marketing/business point of view, retention is
so much cheaper than recruitment. The very nature of the dance, the forrmat, the teaching, the entire organisation is set up to make it as approachable and un-intimidating as possible.
Given all this effort, you pretty much have to say that if someone goes to a decent Ceroc class and doesn't really want to come back, they don't really want to learn to dance at all (the weirdos...
). Ultimately, you have to do
some learning and work at it, you have to put some effort in - and lots of people aren't that keen on doing that.
For example, I tried to recruit my sister a couple of years back - she can dance, I know. I dragged her along for a few times, but she was never that enthusiastic, and gave up after a couple of months. Some people like it, some don't - just because you do, doesn't mean your friends will.
