Cash is still king here in the US. We can't even kill the penny (1¢). My daughter (she's 15) routinely picks up a few extra bucks from all the change people drop and don't bother to pick up. For myself, after COVID I stopped doing that (picking up change).You can’t pay by cheque in the UK anymore. Probably for 10 years or more. Lots of bars etc won’t even take cash anymore. We don’t at the stores we have at work. That stopped around Covid and many didn’t start again.
As to checks, yeah still a thing too and still accepted at major businesses. A lot of small business stopped accepting them decades ago though for the reason that they often bounced.
Americans still get a paycheck, although a lot of us have opted for direct deposit. You do have to opt-in though as you'll get a check if you don't. A lot of people do not have bank accounts though so check-cashing is big business.
And then of course, there are the older generations who will not be denied the writing of a check.
