PR Opinions describes some "interesting" analyst reactions at a meeting recently:

• Sorry you can't meet with Analyst X because according to our records you briefed him/her eleven months ago and as you are aware non-clients can only brief a analyst once in any given twelve month period
• Thanks for getting in touch.  Unfortunately we never made any progress in working together and our analysts have to keep a balance between client and non-client work.  Why don't you see if there's an opportunity for us to do some business and come back to me.

That sounds just like the kind of "pay me and I might have an opinion you like" behavior I've come to expect from my favorite group of analysts. There are decent analysts out there, you just have to look carefully.
