I guess I'm going to be the odd one out. I actually have a really good relationship with my vet and all their employees. I was actually going to make a post about this at one point but never got around to it. This is my experience.

Whenever I have a free couple of hours, I like to just stop in and say hi! Not all the time, but maybe once every two weeks or a month. Every time I like to bring in a pet and they love it! (the employees). It doesn't cost me anything and it's not actually a vet visit, but they do get to look at my animals. They work at a vet hospital because they love animals! They probably rarely get to see snakes! So I would definitely recommend just stopping in. On top of that, sometimes I bring them snacks or cookies... (this will be between you and me) but I have received free checkups and discounts.
Also, by doing this, it has helping me in emergencies and on weekends when they're closed. I have all the cell numbers of everyone and they welcome emergency texts! This actually happened with my snake.. I was able to send the vet doc a picture and she texted me right back with what to do!

So I know I'm kind of blabbering, but seriously, it doesn't hurt to just stop in.
