Used to have to go out to make calls when we were first married as we had no phone. Put money in the slot and dial. As for mobile phones they were the thing of science fiction!
Used them until I was 19 as we never had a phone, press A if you got through and press B if no reply to get your money back.....as kids we stuffed paper up the return slot and checked later and always got a few pennies....my life of crime..lol
