You don't see many of these around anymore. A rare glimpes of how public communcation use to be commonly handled in the past. One of two in Markham (Maybe. Correct me if I'm wrong). Still functional and in operations. One can be inconspicuous by pretending to make a call using the pay phone.
A telephone booth, telephone kiosk, telephone call box, telephone box or public call box is a tiny structure furnished with a payphone and designed for a user's convenience; typically the user steps into the booth and closes the booth door while using the payphone inside.
In the United States and Canada, "telephone booth" (or "phone booth") is the commonly used term for the structure, while in the Commonwealth of Nations (particularly the United Kingdom and Australia), it is a "phone box".
Clark Kent rarely used a phone booth to change into Superman in the comic books era. the phone booth change isn't often seen. Yet Jerry Siegel and Joe Shuster (creators of Superman) used a phone booth for Clark Kent to change into Superman in a Sunday newspaper comic strip in late 1942. Clark, seeing that there is a job for Superman, excuses himself from Lois by arranging to be called away by a bogus phone call. While inside the phone booth he says to himself, "This definitely isn't the most comfortable place in the world to switch garments, but I've got to change identities - and in a hurry!".
