A Santa was spreading something less than cheer at Madrone Art Bar over the weekend—by insulting people looking at his artwork. In what SFist terms "performance art gone wrong," photographer Sawyer Forbes (a pseudonym) began insulting and interrogating patrons, and had to be thrown out of the bar. On Facebook, Madrone apologized for Forbes' behavior. "If you are one of the people he insulted, please come in to let us know and your first drink is on us."
