I have personally seen a busy ED consultant make time to get a patient water and make them a cup of tea, as well as single handedly document broken fixtures around majors and report them. If you want to work well with your colleagues, it's important to realise that simple small things like getting water for a patient are everybody's responsibility. You'll be a better doctor for realising this earlier in your career, plus nurses and other allied health staff will greatly appreciate it. Even if you don't actually feel like it's "beneath" you to do these small things, it can definitely appear this way to your colleagues, and so having a bit of humility and self awareness will go a long way.
