Magnit (grocery chain) in Krasnodar: https://en.m.wikipedia.org/wiki/Magnit
Cities all over the country as small as 50k have these stores and their competitors where you can buy fresh Mexican avocados and sparkling new Korean appliances.
Or, if you don’t want to go in store you can buy any item under the sun on Wildberries, Ozon and have it delivered to your front door.
I've also heard (from Russians) that water access in rural Russia is poor.
I've been to grocery stores in Moscow, btw.
Russia is huge, yes - there are some very isolated places with poor people and without some utilities.
There’s also a lot of weekend (part time) dacha summer houses that don’t have full utility hookups.
And large portions of the population still cannot afford one.
The intersection of those two frequently ends up in the army, as that is the only social mobility they know.
