Yeah, it’s the screening that’s free. If that turns something up, then it transitions to “care.”
I’ve had the same experience with “wellness” check-ups: if I mention some complaint to the doc during the visit, it suddenly becomes “visit with complaint” and costs me $120.
And X-windows. There’s a few server tasks that I just find easier with gui, and they feel kind of laggy over 1G. Not to mention an old Windows program running in WINE over Xwin. All kind of things you can do, internally, to eat up bandwidth.
