Confusion at the bank line

I must say that one day I was working with a friendly yet quite suspicious attending.  We had a few cases together. Anesthesiology. I was to visit and see the patients prior to surgery, get their preoperative report done and prepare the OR.  I was called to visit a patient named "CR".  CR was going for an OB procedure.  A hysterectomy.  I went and found her on the floor.  Due to some unforseen reason, her surgery was cancelled.  OK, easy enough.  15 minutes later I am in the OR area and I am told that CR is coming for her surgery.  I told them that "no she was not".  A minute later a patient enters the holding area and the OR is not ready. Turns out its a completely different CR and her surgery is exactly the same.   What are the odds.  My attending was not happy at all.  She was not forgiving and she did not even know or understand the mix up.  I am sure I am judged incompetant in her memory.  Sad.  Trouble I was unable to avoid.
