<human>: Give me the gist of the text in a nutshell

Reddit, the other day I completely "judged a book by their cover" and turned out entirely wrong.

Just for some background: I am walking home along at around 9. Light enough to see outside, dark enough to be in the sketchier part of the night. An extremely large African American man around 28 with tattoos visible on face and arms (wearing a tshirt and jeans) is close behind me for about half of my street. I start to get a weird feeling, considering I'm carrying a backpack with all new clothes and part of my paycheck inside, so I turn a few corners and take a longer route. Once I turn the second corner I turn and see no one anymore and feel a little safer until all the sudden I hear a man screaming "HEY" and turn around to see that same man turning the corner, running fast holding up SOMETHING (remember still a little dark). I move a little faster until completely paniking and just saying "Im sorry!" and turn around to the man smiling holding out my wallet that had fallen out of the rip in my shitty backpack. I get so embarrassed and offer him around 40$ to which he replies "Sir, if I wanted your money I could have had it. Have a great night".
<bot>: Huge scary guy with tattoos following me, continues to follow while yelling even when I go to scenic route, I begin to shake like a little girl, he catches up and gives me wallet, refuses reward. I was embarrassed
