He hired them. The ones he bought fled back to the friend shop.

Yup, true enough, but that's cos the alcohol reduces the production of
anti-diuretic hormone, which is the control hormone you use to moderate
the water volume in your blood. You reduce ADH, your liver seperates
more water from the blood and sends it to your bladder; the alcohol
content shouldn't be any higher than your blood ABV. This is,
incidentally, the reason that you end up dehydrated after a night of
drinking large volumes of what is mostly water.

A challenge some of my students see as being a personal one, it seems...

Fair enough, but those are designed to check whether you are above a
specific none-zero value, and it's sensitivity is adjusted accordingly.
If the limit were re-set to be zero, then different units could be
used, which would be more sensitive, IYSWIM.

Makes no difference - unless they intend driving home from that party.

Of course. But if intending getting so pissed I'd still be over the limit
the next day would go by PT or cab.
