Must have been an airport somewhere in the 1990s.
One pay phone call I recall was from a phone on Broadway, Upper West Side, NYC, in 1981. I used over $20 in quarters for a short call to my then girlfriend (and now wife) in Japan. Seems to me I spent more time listening to the kerchunk of quarters dropping than I did to her...
Nowadays I find Skype just amazing.
Or how about letters? When is the last time you sent a letter just to communicate with family or friends, rather than email? Or received one? And no fair counting thank-you notes or birthday/Christmas cards. I think I kept up the letter habit longer than most as my mother, God rest her soul, never did learn to use email or a computer, other than for playing solitaire. So until she passed in 2011 we would exchange the occasional letter in addition to weekly phone calls.
What was nice about letters, when you were far from home or away from someone you cared for, was that you could treasure the letter, taking it out to read, over and over. My mom kept every letter my father sent her from the Pacific in WWiI, and he kept many of hers as well. We still have those.
