I got mine at Planned Parenthood in Hayward, CA. Like you, I am a VHEMT volunteer. I did not have to argue with them at all. I wore my ZPG t-shirt and told them why I was getting it and they said "OK". (It was a lot better than trying to go through my company's insurance's urologist, who refused to do it because I was "too young." (I was 28 at the time.)) Getting snipped was the best thing I've ever done.
