Access card.
I used to freelance at a place called Filmcore on 5th Avenue in Manhattan. The building had a security guard and if you didn’t officially work there, you had to sign in. Every day I signed in as Raoul Duke. Of course, the guard never checked the validity of my name, or else it would have come out that I am in fact, not Raoul Duke. I wonder who else signed in there? John Lennon? Oscar Mayer?
I worked there long enough that they gave me an access card. Again, I requested it under the name Raoul Duke. As you can see, my request was granted.
Nice to know that the security is tight in NYC.
