Being happy in a practice environment like that would require a substantial change in mindset. I think most of us want to practice prudent medicine, performing the right interventions and investigations as the right time, attempting to minimize over-testing and treatment, along with the inevitable increased costs, complications and anxiety (of course, with a little CYA sprinkled in).
In order to thrive in job like this, all that goes out the window (even moreso than it does for us everyday). You just need alter your ethos and be enthusiastic about providing bad care. "Feeling a little under the weather, maam? Sure let's make sure to check everything out. First here's a prescription for Zyvox and Cefdin (only plebs still use z-paks), I'm ordering a CT S/C/A/P and an echocardiogram. If that doesn't show anything we'll get an MRCP and a PE study. The nurse already has the results of the CBC, CMP, TSH and Troponin. Luckily everything looks okay so far, but I do have bad news. You'll have to wait 12 hours for the results of your testosterone and free cortisol tests. We'll call you right away though."
It's Veers-style widget medicine, but w/ a smile and forced enthusiasm. And you get 240k a year in NYC.
