> If you're negotiating deals worth billions of dollars, or even just millions, I'd strongly suggest not doing so with a hangover.

...have you met salespeople? Buying lap dances is a legitimate business expense for them. You'd be surprised how much personal rapport matters and facts don't.

In all fairness, I only know about 8 and 9 figure deals, maybe at 10 and 11 salespeople grow ethics...

I strongly suspect ethics are inversely proportional to the size of the deal.

That's more an indictment of sales culture than a critique of computational efficiency.

Well sure, because you want the person trying buy something from you for a million dollars to have a hangover.
