I'm starting a new Escrima class. So far it's just a few people and most of them are damn near broke. We work out at a park and I have plenty of equipment, I have no overhead and I don't care about the money. But I do care about commitment. On the one hand, my instructor isn't charging me a penny, but I've known him for 25 years (once he was my student in another art) and I do my best to find ways to show my appreciation (one of which is starting this class). On the other hand, it's been my experience that the typical student values what they pay for. If I don't demand a minimal cash commitment, they drift away after the novelty wears off. What do you think?
