Well, speaking of one of our personal doctors..........I got a bill from him and a few others that we never met before, I had to explain that in my eyes he was a contractor of services, and I sure wouldn't pay for any contractor that I have never seen show up on the job, nor would I pay a contractor to give the first one a different opinion, needles to say , he saw my point, and I recieved canceled bills shortly afterwards!
And to just be frank........If I got a bill from the vet and our doctor at the same time, I believe I would pay the Vet's bill first! It's a farm thing, I am not sure others would understand.
