Your perspective on the "revenue" side is particularly helpful. If there was any indication that the class could not accommodate beginners or returnees, I didn't see or hear it. I did, however, contribute to the revenue just like everyone else, and I didn't see anyone putting their hand over the donation box and ascertaining whether I'd get my money's worth. (I did, but no strictly in yoga terms, you know?)

I appreciate the tips and tricks. I'm unlikely to do anything with a DVD at home, but I'll certainly be seeking out a more "yin" instructor and class. And I'll remember that about the elbows and hands! Thank you.
