I went to the ER several years ago and the admissions clerk just became surly over the fact I told her I was not pregnant, and I understand people lie but it just became ridiculous. She finally said, in not a very nice tone, "How do you know that you aren't pregnant?" I looked her square in the face and said, "I haven't been exposed." She laughed and then began sharing what I said with her coworkers. Oh how I wish I had a better spine then, but I carried my point.
