I just think it is part of the ballroom dancing business that the professionals flirt with the students. That is why I am not smiling or anything around these people. Their "niceness" is just part of their money-making scheme and the amateurs are their victims/moneypots. .
I absolutely disagree. Sure, there may be a few instructors that function this way, but not most.
Ballroom is fun and social. Ballroom is also very physical - both in the sense that you touch your partner/students, and in that you're moving and communicating a message with your body. And in private lessons, you get this fun, interesting, skilled, often very attractive person-of-the-opposite-gender's attention for a whole hour, and they're touching you, and they seem happy to be with you (because -
gasp - they enjoy their job!). It's easy for an unsuspecting student to take all of this the wrong way, but that doesn't mean the pro is doing anything mean or manipulative. They're just being themselves.
And seriously... why turn a fun hobby into something where you're "not smiling... around these people"?
If you just want to be a social dancer, people who care about your progression should probably recommend one private for every 5 group classes and then social practice should make up 10 times the amount of time you are spending in privates. .
Maybe that works for you, and if it does, great. Personally, I dislike group classes. Past a certain level, you can learn steps in group classes, but really learning to lead and follow is very hard in a group class. The difference between a leader who takes a lot of private lessons, and a leader who only attends group classes, is very noticeable - at least in my area/experience.
Either way, I don't think it's up to you to decide that a studio or an instructor is bleeding their students for money because you don't like the number of lessons they recommend.
