Coin-only laundry machines are probably the biggest drivers of persistent cash usage in most of my acquaintances' lives. I'm guessing that apartment buildings big enough to have in-building laundry rooms but small enough to not be able to justify a cashless payment system may just end up shifting to not charging for laundry.
Sample size of one incoming, but the building I live in only has 16 2-room apartments and has a app-driven option for the machines (they take coins, but there's no change machines and I've never seen anyone actually do so)
Until I made the (in hindsight, fortuitous) move into a house with a washing machine, I and many other millions of people in the US used cash weekly at the laundromat. Even their laundry service only took cash.
