What microaggression does the author describe experiencing in "Microgentrification: WE BUY GOLD"?

In this essay, the author describes being scolded by the owner of a pawn shop next to a cafe where he likes to go. The man scolded him for nodding off. After the pawn shop closed, the author finds joy in the fact that it is gone.

In my opinion, this situation is unfair because the author was judged based on stereotypes rather than his actual behavior. I think everyone deserves to feel welcome in public spaces without being treated as a threat because of their appearance or race. This example shows how even seemingly small comments or actions can make someone feel excluded and disrespected.
