i spend a lot of time in detroit, and you can get booze in the corner stores, there. they're called "party stores", rather than convenience stores - there's a specific market for it. i kid you not. given the way i transit through detroit, this is useful to me. if i get out of a concert at 12:15 and want to get to a late night destination that's a 20-30 minute bike ride away, it makes sense to grab a drink for the ride.
i know that a lot of people will frown on this, and i ended that paragraph where i did to produce a shocked reaction, but i haven't lost any limbs yet and don't intend to any time soon. my example isn't exactly widely emulated.
that said, let's address the actual point here, which is the hours that the stores are open. the reason people get frustrated is that they have to go to a bar to get a drink if they can't get to the store before 22:00, or if they just happen to run out early. is 22:00 really a reasonable closing time in 2018? could it not be extended until 2:00?
but, this is just another example of where these parties are on the spectrum: the conservatives are promising to extend the hours available for purchase, while the socialists are in favour of continuing restricted access. then, they wonder why their bases are upside down - why the socialists do better with lawyers, and the conservatives do better with workers.
i don't personally find the status quo to be particularly restrictive, because i just buy more than i need ahead of time and then drink too much.
