Agreed.
Ignore the guy, don't put out any money, and find someone else.
The best thing to do is check the diagnostic criteria, forums, personal stories, etc regarding all the other "disorders" and "syndromes" out there. Even the ones that sound scary. And find out for yourself, decide for yourself, if you have any of them.
But seriously, if someone doesn't let you finish talking, and besides that they decide you're ineligible based on eye contact, marriage status, job status, etc, then they know nothing about you, and probably nothing productive about psychology/psychiatry.
If you DO wind up back there, or with another one who cuts you off... IGNORE them and finish your statement. I was in the same situation not too long ago and rather than throw a fit (since I was seeing an assistant, and the main shrink is next so I don't want to piss anyone off) I simply gave up about halfway through and took over the room for the next 5 minutes, totally ignoring him and saying everything I could think of in relation to the original question he'd asked. Of course, he was probably ignoring me too, but at least I got to be an a@!@#$#@ back.
