1. Obvious bleeding, without a dressing of any kind. One of the basic rules of first aid is if it bleeds -- put pressure on it. This especially applies if you have amputated a body part. Not only do we not want you to bleed to death, but it makes other patients nervous to see dried pools of the blood on the floor.
2. Trying marijuana (or alcohol) prior to seeking medical attention for a traumatic injury. Then not only are you high or drunk while trying to describe what happened -- but if you delay too long, we can't repair that terrible leg laceration you got defending your cat from a werewolf.
3. Not even looking at the injury prior to arrival. We know, lots of people are squeamish -- and that's fine -- but find someone who isn't to look at your cut and at least see if it bled. We are more than happy to do this for you...but we charge a lot more.
