Even if they don't come back, it's still better to have the Groupon chasers in your studio. You get paid at least a little bit if they buy a Groupon, compared to nothing if they don't. The marginal cost to a Yoga studio of adding another student is zero.
Of course this doesn't apply if you're running close enough to capacity that the addition of more students will degrade the experience for everyone else, but a lot of yoga studios don't have that problem, especially not at off-peak hours.
