If the boy was uncomfortable being made to spell it out, it was about to get worse. Michael was working on his sarcasm and while he wasn't really able to tell when it was getting used against him, he was getting okay at using it himself.
He pulled out his notepad and said, "I've never heard of reverse racism. Sounds pretty serious. Why don't you tell me what you meant by," and he copied the boy's hand gesture around the shop exactly, "so I can make sure to note it down for the case file. Be specific."
He wanted to wink at the girl so much, but as Victor had explained to him, he was bad at winking and sometimes people thought it meant he was hitting on them. Michael was absolutely never hitting on anyone.
