I volunteer a couple shifts a week in a hospital ED helping with triage, and I recently had a bit of a run-in with a patient's parents. They came with their son for some unknown pain in his leg, and were insistent that they get bumped up to the front of the line to be triaged. I didn't know how to respond to them but the dad kept saying, "Don't you understand? He's just a kid" over and over, shouting at me and looking like he was about to get violent. I tried to explain that there were other people who had been waiting longer, and that his son didn't appear to be in any serious pain, all to no avail. I get people like this all the time who demand to be seen first either for themselves or their family members, and they never seem to understand that they have to wait their turn. Any advice on how to deal with people like this?
