Wait, someone actually left a cart right against your car door and just walked off? That would send me over the edge, because now you either move their cart or you risk scratching your own paint and it's not even your mess. Honestly that one move tells me way more about a person than whether they walk the cart back to the corral.

Man, I don't buy that pushing back is some magic trick. Half the time you ask a question and the doctor just nods, says "good question," and gives you the same spiel they give everyone. I've asked about my cholesterol meds twice and got two different non-answers. The 15 extra minutes you got sounds nice but that could just be one decent doctor, not proof that arguing works. The guy in the waiting room timing his visit might've had a doc who was already running behind and felt bad. Push back too hard and some of them write "difficult patient" in your file and you never get taken seriously again.
