“There’s no need to fear! ...”

Can't. My back hurts.

I was in one a few weeks ago.

It's been so long since those could reliably be found, that even the 1978 Superman movie has a gag about it (Clark steps up to one of those stand-style payphones, briefly looks befuddled, then runs into door turnstile instead, super-speed changing while it spins)

Bonus points if you've used those equipped with a rotary dial.

The other week, I was dining at the Old Spaghetti Factory, and their lobby is impressive for classic furniture and cool stuff on display, including a Donkey Kong and a (nominally) Ms. Pac-Man cabinet, and some "Fragadas Españolas" models.

There was also a bona fide telephone booth in there, in wood and glass, and I absolutely went nuts, actually needing to place a phone call. But I couldn't quite figure out whether it would open and admit me, or if customers were supposed to be fiddling with it at all, or whether it was only a showpiece. So that exploration will wait until the next time I drop by.
