I mean, we're talking about drunks here.

Asking an alcoholic to pour out any kind of liquor is mind-bending to many of them.

Look, you and I both know that it is literal poison, but, again, it's lushes we're talking about.

0.5% is already too technical a term here. What is that in glasses or drams? What do you mean you can't convert pints to percentages? What commie bullshit is a millyliter? Fuck you, I'm getting hammered for cheap!

If you can get a meme going to always piss on your first pint in the toilet, then maybe, just maybe you can get it to work.

And, yeah, a lot of drunks are no longer allowed to drive cars and really should not while drinking too. Doesn't mean they don't do it though.
