@Will@peter Security pen testers frequently do things like carry a clipboard with checklists and pen on a cord attached and carry other props like a box of donuts and a carrier of coffee in order to shoulder surf their way into what are supposed to be secure entry buildings and walk around inside them. If you dress appropriately for the situation, not only are you invisible but people will actively help you gain entry to places.
@peter And I guarantee I have more education / experience than most of these folks, and most the time I dress like them too, but you put that yellow PPE on, and you aren't there anymore.
It really explains how a half dozen guys could just enter a museum on a cherry picker and leave with priceless art... clearly if they have a machine and hi-vis, they must be doing something on assignment, leave them alone to finish!
@peter It illustrates the power of the hi-vis vest, a topic on which I am an expert. I think what it also reveals is a powerful understanding about class structures. When someone is wearing one, they are assumed to be a worker on legitimate assignment, and people treat them as such. When I wear mine, I typically get better service from cafe workers and servers/cashiers at lunch, but business-y people treat me like I'm invisible. Not bad, just they don't acknowledge that I exist.
