Payphones were mostly extinct even when I was a kid. I didn't have a cellphone either and smartphones didn't exist yet, except for the extremely rare Blackberry. But it wsn't a problem because basically every establishment around me had a landline phone I could use in an emergency. Now even landlines are extinct because just about everyone has their own phone on them at all times. Phones are easier to come by now more than ever. Kids have never been safer, even without their own phones.

Even when I was teen back in the 1980s while payphones were still going strong, they weren't everywhere you wanted them to be. My mother had a standing rule that if I was going to be out past 10pm, I had to call her to let her know. Depending upon where I was, it was often a pain to find a payphone before 10pm so I didn't get in trouble. If I had an emergency, it wasn't at all guaranteed I'd be near enough to a payphone for it to be helpful.
