I don't know why I get the feeling, these are the big things changing. Maybe because something common just disappears completely.
I remember us "travelling" to Eschere Wyss Platz to call abroad as the one there had been "broken" for months and months as in the calls were free.
Of course I wondered when they put up the first one:
<<Die erste Telefonkabine wurde 1881 in der Fraumünster-Post in Zürich eingerichtet.>>
The first telephone booth was installed 1881 at the Fraumünster post office in Zurich.
1881? That kind of impressed me too
