Well, he was working at Shades Darker so he was carving out a reputation for himself as sexy on two legs + go to man for "acquiring" things. He might've also bragged about his name/his codename to clients.

So probably people would be able to describe what he looks like and some places he might've liked to go off his shifts. He's also fairly buddy-buddy with Venom, a bartender at Shades Darker.
