That's how mine is. Never says 'Okay, I want to see you again twice a week for the next few weeks' or anything like that. He just tells me to come back when I feel like I need it. Sadly, I went through a few of the worthless kind before I found him. All the others acted like they did something, but I could never feel anything actually happen, nor any difference as a result of it, and they'd all spew the same type of nonsense that was all over the OP's description.
We do need to be clear though. These adjustments we are discussing are simply back cracking. That being said, like foam rolling, if it helps do it. Your spine is not of alignment. I really like the "The Joint" business model. It's treated like a gym membership or a massage envy. You pay for a certain number of visits, and just walk in and the chiropractor cracks your back a bunch of times in funny ways. No talk about ying and yang, spinal alignment or any of that other stuff.
