Honestly, these days, you'd be better off teaching them to borrow a stranger's cellphone than go through the effort of trying to find a pay phone.
It is an antiquated and unnecessary skill.
Oh, for crying out loud. Why can't they learn to do both? I'd prefer they use a pay phone rather than hassle a stranger (who may not be friendly or willing to lend a phone in the first place). But if they couldn't find a pay phone, then asking to borrow one is reasonable.
I've been in situations here in town when the only ones around to ask have been businesses or offices, and they absolutely will NOT let anyone use their precious phones unless they're a customer/client. And even then some say no.
The public library said no, when I really needed to use the pay phone and it was being hogged by a guy who was chatting about nothing in particular and I needed it to get a cab. So I asked the librarian and she refused - just dismissively told me to find another pay phone somewhere else. Since I'm physically disabled, not very mobile, and part of everyone's property taxes go to support that damn library, the least they could do would be to call a cab once in awhile if someone really needs it and the pay phone is tied up.
Hell, I've USED a rotary phone and I'm not even sure how to use one.
Begging the question: why in the hell would anyone need to know how to use a rotary phone? They're practically museum pieces now. Maybe if you got locked in the basement at your great grandmother's house and have to call 911 because she's forgotten she has a basement and thinks you're a ghost...
ON THE OTHER HAND, I continue to be puzzled and slightly frustrated by kids who don't know what a VCR is.
It helps to know how to use a rotary phone because it might be the only phone available. I had one as recently as 7 years ago.
As for VCRs, I still have one, though it's not hooked up. I got rid of most of my tapes, just keeping ones that aren't replaceable with DVDs. Oh, and I made sure to keep my original Star Wars trilogy - the one that was released before George Lucas decided to "improve" it.
There's just no reason for them to know. If I had kids at an "appropriate" age, they would be 5-10 years old right now, well after I stopped owning/using a VCR. They'd never have even been exposed to it.
Believe it or not, there's stuff available on VHS that isn't available on DVD.
Kids would be better off learning how to build a fire, grow vegetables, and tend livestock. There may come a day when those skills are necessary for survival. :/
If they ever go on Survivor, the million dollars can come down to whether or not you know how to build a fire. There was one season where the contestants couldn't even manage it when given matches.
The odds of them a) needing to use a pay phone, b) finding a pay phone, and c) having quarters to put into the pay phone happening at the same time are just so tiny.
Which is really strange, since it's something I expect to have happen the next time I take a taxi to the local mall. If I decide to get the taxi to pick me up somewhere other than at Walmart, I'll need to go to the pay phone, put in two quarters (local pay phones cost 50 cents here), punch in the number, and tell the dispatcher where to pick me up.
There's something to be said for keeping one foot in the past so one isn't blindsided and helpless the next time there's a power outage.
