Completely agree. The broader problem isn't an ethics issue, but that the topic itself might not be the best choice for a personal statement. Yes, there are people with compelling interactions with medicine as a patient, but using that as the focus of your PS opens a huge can of worms. You should have many more compelling reasons to go into medicine that now come from an almost-practitioner's standpoint, experiences you would have had to confirm your career choice *after* whatever event you're describing happened to spark your interest. If you don't, and just want to go into medicine because of an interaction you had as a patient, that raises red flags as those applicants have a higher chance of not really knowing what they're getting into (and ultimately drop out of med school). And maybe, probably, that doesn't describe you at all...but it makes the reader start to wonder if that IS the case and can work against you. Also, I'd be a little wary with the example you described unless it's couched in a very strong context...on it's own, a doctor slipping you some extra free meds doesn't seem like a life-changing event to me.
