Sam overhears two patients in the waiting area of the physician’s office communicating in their native language, which isn't English. One of his coworkers, Paula, comments that she finds this offensive because the conversation may pertain to her or other coworkers. Paula tells Sam that she's going to tell the patients they need to speak in English, even though they're still sitting in the waiting area. Sam immediately advises Paula against doing so, and tells her that all health care workers need to be accepting and sensitive towards others' cultures. What else should Sam do if Paula refuses to listen?
