Omg I'm so sorry you went through that. Did it not occur to them that you were anxious? My BP is always taken twice when I see my doctor - first at the beginning, and then again before I leave - and it's always higher in the beginning before I've had a chance to relax. But you were there for a procedure, which is more nerve-wracking then a simple appointment, and I'm sure being told your BP was high in the beginning did nothing to help calm you down.

I know this post is a few months old, but I hope you had a better experience when you went back!
