That works so excellently for the military. You’re technically able to be called back in at any time, but you’re also allowed to drink when you could reasonably expect to have that time off.
And the clincher; you’re not allowed to be drunk on duty, so they can’t even say “no worries, I’ll pick you up” without implicating whoever ordered you in
Even more so, it’s turned into a hot button topic where people will be actively pissed of at you if you try to bring it up in discussion, calling it a “dog whistle” for nazi / anti-women ideology.
