Yes. I remember pagers and pay phones when I was younger. Now you can contact anyone immediately.
I remember the is a small structure furnished with a payphone and designed for a telephone user's convenience named telephone booth
Haha. You are correct. I remember when it was an actual booth and not just a half booth. During the winter I would go inside one when I was waiting for the bus in Manhattan.
