True story - An accountant in his sixties sells part of his practice. Keeps a few favoured clients and stops paying his Institute subs. He tells a friend that "My clients don't care whether I keep paying my subs etc and I don't need the pressure of prospective visits from the Practice Assurance team - or anyone else." The friend reminds him that he won't be able to describe himself as a Chartered Accountant any more or to give references that rely on that description.
A few weeks later the accountant meets his friend again. "I remembered what you said about references so last time I was asked for one I simply put "Ex-Chartered Accountant".
"How did your client respond?" asked the friend.
"Oh - I think he was pleased. He didn't say anything but I heard him later telling someone I was an EXcellent accountant."
