Demanding patients

Just spent time on a hospital ward with a family member and was reminded how intolerable some people can be, demanding this and that from busy staff. Thinking they are the only person on the ward or the most important and ringing the bell constantly - seeking attention, the wrong kind!! My relative told me there were quite a few people waiting for day surgery and time was ticking by, this guy in the next room was furious to have to wait. The nurses explained that it was the surgeon who had been delayed and that the knock on was affecting everyone, not happy he persisted in being rude and demanding to the nurses...... other patients were witness and found this guy v v annoying. It's tough out there and nurses have a lot to put up with!!!
