Sort of follows on from the thread about people expecting free advice. I recently had someone absolutely insistent that I take their case despite being told that I simply had no time, and that if I did take the case I wouldn't be able to do it properly. He even threatened to report me to my professional body unless I agreed to take him on. Needless to say, I told him to feel free to do so.
Why on earth would you even want to put your trust in someone who was telling you they had no time to give you the help you need and who has had to be forced to take your case by threats?
