Although there's many, I will share 1 of my earliest memories/examples from when I was a Student. For context I'm a Paramedic in the UK. We attended an elderly Asian male, think in their 60s, with acute abdo pain and vomiting (I was '3rd manning' with a crew of 2). Taking care of elderly/parents is a huge deal/value, and we received a detailed history alongside records of regular obs from the family. Knowing this, since family were concerned, I was concerned. I apply a similar principle to parents and children, that parents are more or less experts as they know their child best and them being worried is a red flag - hence in this instance family concern was a red flag. The crew I was with was very dismissive, despite the red flag of recent overseas travel. It must have been my 1st/2nd/3rd shift in my first year. It was telling, as it prepared me for the discrimination I would go on to keep encountering. Moreover, it underlined the type of Practitioner I DIDN'T want to be and pushed me to change this, starting with my own practice.
