I was fortunate in that I rode a bike to work. Nobody stops the guy wheeling a bike. It’s very clear, I’m leaving. Gtfo of my way.

In the military you would just grab a manila folder and walk very fast. Most people would assume you were running an errand between offices and would get tf out of your way

Do the opposite, don’t make eye contact and walk fast. The good old fashioned diarrhea walk. Anyone tries to stop you, tell them whatever poop related excuse comes to mind.

This is how I learned to walk silently and swiftly with heavy steel tipped shoes
