Working in the veterinary field, you meet all walks of life.
The clients who spend $7k on a purebred puppy who then needs several thousands more in surgeries to help him live a normal pet life (and may also end up on lifelong $$$ medications, given the breed predispositions to certain chronic diseases).
The older clients who complain to me about caring for multiple pets on a fixed income, and then show up next month with a new kitten or puppy (or two, you know, because they need a playmate). I get that pets are expensive, I don't set our prices, but you went and made a choice to add another animal to your family. And then complain about how the young animal(s) have too much energy, are destroying their house, pull on the leash too much so they can't walk them safely, etc.
When I was in school, I worked with clients who chartered a flight from NYC to our teaching hospital to then spend at least $20k on cancer treatment (surgery, ICU stay, and chemo) for their dog. It was a super cool cutting-edge surgery that was awesome to be a part of, but I couldn't imagine spending that much on a pet.
I could go on forever, but I won't since I intentionally let most of these kinds of stories fade from my memory (helps stave off burnout).
