Leaving a "tip"!?

A man in a restaurant in that London place we hear so much about has cut off his penis in front of bemused diners. Surgeons at the hospital were apparantly UNABLE to reattach it.

Sweet child of mine, if was short of cash he could've just said "I'll owe yer". Either that or perhaps it was a drunken bet gone wrong, but FFS, I'd need a hell of a lot of ale inside me to even contemplate a steak knife coming near my prized marrow aka purple-headed warrior etc [insert psuedonymn here]
