When I worked in health care, we would have patients come in all the time that didn't have their lab orders, so then would blame us for losing it or not having it on hand. There was this one incidence where I had a patient come in, they didn't have their slip. I tried to explain to them that they needed a slip from the doctor, so I could put their orders in the system, so we could draw the blood work for them as a phlebotomist. They decided they were going to scream and yell in my face, call me nasty names. I sat there and then I told them, I can do my best, I can try to call your doctor's office if you don't want to, I can try everything I can, so I did. Luckily, I was able to get a hold of their doctor's office for them, then we drew their blood for them. It was almost to the point where we almost had to call security because they were getting very violent, but I pushed it aside and did what I could to get them in and out as quick as possible.
