You can use "a name of your choice" to reserve a spot at the play about the Sterling Hall bombing.

And you won't need to show an I.D. at the door. I was wrong about that, I've been informed.

You simply need to get your name on their list and then tell them your name at the door. And if you don't want your real name on their list, you can use "a name of your choice."  Like... I don't know... Robert Fassnacht... or Leo Burt.

With no I.D. requirement, appropriated names suggested, and a play whose playwright asks "why do most of us think that [those who broke the social norm] weren’t [justified]?," wouldn't you expect some theatergoers without reservations to attempt to get in using a name they think somebody else might have chosen?
