Whereas the commercial f/l washer/dryers in my building’s basement do their thing in an hour for a normal load. Combined. It’s actually faster than doing it in your own laundry if you come later on a week night since you can dump in 2-3 loads at once.
And getting back to SD, plenty of apts in areas 1-4 have either a laundry room in the complex or a laundry closet.
Personally, I’d rather just have building laundry and pay for some other poor SOB to deal with maintaining the machines.
