I agree and we actually have the same policy in place where I work. We’ve also added that here must be 3+ people within 5-minutes of class starting to hold class. It truly doesn’t make the time for an instructor worth it, with only 1 or 2 people. Otherwise, it could be considered a “personal training session” or “small group session”- which isn’t what the class is! The policy is in place for a reason, stand by it!
