Is time poverty a thing now?.....
Well, yes if you work irregular hours with irregular days off.
Lucky here in Scotland all is open mostly 24/7, with a bit of organization and with the internet I manage fine to feed myself, the cat, buy unnecessary stuff even when I am on shift 2 weeks in a row.
Once we had an unplanned event at work, I left for half an hour to go to my hairdressers appointment (just as well she was on site), while another colleague went home (10 min walk), took his Tesco delivery in, came back to work

I have an agreement with my postman to leave parcels in a safe place, I also make extensive use of the click and collect services, pick up the stuff on my way home with the bike.
There is a local shop just across my door, opens long hours, still some weeks I leave before they open, get back after they close.
Not condoning the short distance driving, btw: I don't have a car, and the (less than a) mile to Aldi's gets walked unless I'm already out on the bike.
