Hey, biscuits are important. My sympathies are with Sir Fred. How would you feel if you were expecting a chocolate hobnob but only received a rich tea (or a pink wafer in the case in question)?
Admittedly, it might appear somewhat draconian to threaten disciplinary action, but when you're the boss of a multi-million pound empire, is it unreasonable to insist on your chocolate hobnobs?
I'm a plain digestive man, myself. Or something.
