I have this funny feeling that tomorrow morning's shave is going to be substantially more difficult and noticeably less comfortable due to this afternoon's episode of drinking and shaving.
A diamond martini, inspired by my recollection of the tale of a diamond martini from my youth (see below), coupled with my 1956 Gillette TTO and a face full of lather resulted in a chin possessed of less skin, more blood and a throbbing "hello".
Don't do it.
Unless a pressing social engagement requires you to shave after having imbibed of a massive martini, I would err on the side of a fuzzy chin.
Just a thought.
