Just threw a dude out of the coffee shop for the third time.
He has been repeatedly told not to return.
He keeps coming back.
He does it specifically to make the staff uncomfortable.
Today, he lied to my face about who he was, and then demanded a reason for being expelled.
I told him that he knew very well what he'd done, but he continued to argue for a minute until the woman he was with was like "stop, just leave. You're embarrassing me."
