Your peer (a first line supervisor at a major retail store) is conducting

a performance evaluation of a subordinate in the break room, where numerous other employees are eating lunch. Your peer is raising their voice and noticeably frustrated with the employee. The employee is attempting to defend their position but it is obvious your peer will not let them get a word in edge wise. You notice numerous other employees shaking their heads. You decide to approach your peer (also a friend) and address what your saw. What do you say?
