I do get to listen to pre-meds complain about having to get 50 hours of shadowing every once in a while.
(But it might be harder too because people don't want random students in their appointments etc. Our hospital for example is very strict about how often they can come to shadow. Something like once or twice a semester.)
That's interesting, because it's true. Some people can get lucky though. Storytime!
Way back in the dark ages, I was actually pre-med (only for about 5 minutes, I swear!

).
I was INCREDIBLY lucky: my best friend's father is a neurosurgeon, and a really interesting, driven, "nobody gets in my way," off-the-wall guy (then again, don't you have to be, to do that kind of work?). Anyway, none of his children had ever taken an interest in his career, but when I asked him if I could shadow, he literally laid out the red carpet for me. Needless to say, he pulled quite a few strings for me. And while I *did* fill out the necessary paperwork and did the TB test required to shadow in the hospital, to this day I'm not sure how many rules he violated for me... I got to watch a brain surgery on my second day of shadowing him. The nurses were giving me hell when I first got into the OR, essentially telling me to shut up, sit in the corner, and not move. Well, in waltzed Dr. Awesome, all scrubbed up. He pointed directly at me, and paused for a moment while the PA, nurses and anesthesiologist all looked over at me. "YOU," he barked, "Do you want to be a doctor?"
"Yes," I squeaked.
"NEVER sit down. Get over here!!"
I want to say he plopped me in front of him, and did the surgery with his arms around me, because that's what it felt like. There was a human brain, like two feet from my face. Being 16 at the time, the whole experience completely blew my mind. He also introduced me to all of his colleagues, and gave me lessons about anatomy, study skills, bedside manners, and much more. No one, in any pre-healthy field, could ever dream of having a more enthusiastic mentor. What a guy.
My parents were actually a little bummed when I switched to pre-vet (read:woke up), not just because of the financial implications, but because I wouldn't be able to shadow this guy anymore.
Interestingly, I had to start from scratch when it came to getting experience with veterinarians. I knew only ONE veterinarian, and she had been retired for some time. We didn't have a family vet because, *gasp,* we didn't have any pets! Nevertheless, it was easy to connect with someone. Also of course, as you said, vet clinics have more flexibility and self-governance when it comes to safety and patient privacy protocols.
Wow, lengthy. You can tell that I'm procrastinating on something...
