I once got an e-mail from someone working in IT support at a Canadian bank with: MBA, CFA, FRM in his e-mail sig... felt a bit sorry for the guy, he'd gone to great lengths to get those qualifications and yet was still working in support. I'd have been inclined to drop them from the sig if I were him... tis like having BA(oxon) on your McDonalds name tag....
Crikey, that must be pretty rough for him!
