Former security guard on a variety of different kinds of posts. This is 100% accurate for anywhere that doesn't require ID or a scanner card or some shit.
And act like you ain't got time for anyone's shit.
I've worked events, and carrying a 6' ladder with hi vis and a dome shell while grumbling is instant access wherever you need to go. Just make sure to not stop and look around cause your cover will be blown.
So on most sites, black i s reserved for management. Management goes where they want but also come up randomly from head office so no one questions that they haven't seen you before.
Also works for inside locations if you are carrying a large bag of food or several pizza boxes. I've snuck into some concerts with the pizza box method.
I feel walking up, talking on the phone, sounding pissed while flipping through the pages alone would open a lot of doors. Don't need to be too charismatic when you look like some tiny bullshit away from crimes against humanity.
Then you just wait until somebody enters in.
When the person opens the door you run to them and yell "wait wait wait" while frantically gesturing. After you enter - say quick "thank you" and disappear.
It's all about projecting confidence that you are the person in control. Don't even need the right clothes or a clipboard. Some of my favorite scenes from the Beverly Hills Cop movies is when Axel does this kind of thing. Catch people by surprise, flash an ID without showing it, look pissed. "Is that your Porsche outside???"
Most restrictive areas you can walk in completely nude with A four story tall T-rex and no body would notice.
Or more accurately no body would care because it’s not there job to care
My point is, most of our restrictions in life are our own making and when we allow ourselves to succeed not even the angels can stop us, or some other bs self help saying
The most charismatic man I know is my uncle, he worked right near the WTC on 9/11 and even though they closed his bridge home because it was 9/11 he sweet talked his way across.
