<human>: Summarize the given text in a few sentences.

I'll start, on Sunday I went to the theater to go see a movie, the theater was near full capacity. During the previews a woman who appeared to be in her mid-30s approached a man who had cerbral palsy in the handicapped seat and sort of demanded (not asked) that he give up his seat to her. He kindly asked why, she took an awkward pause and said that she had later stage Muscular Dystrophy and she wanted his seat since it was difficult for her to walk all the way to front. 

My bullshit alarm went off immediatley since she had none of the symptoms of MD. Her muscles looked perfectly normal, she had no trouble walking when she was outside of the theater. This woman obviously did not have any kind of MD. The poor guy with cerebral palsy gave up his handicapped seat to allow her to sit there. I went and got a theater employee to get his seat back, the employee asked the woman to provide some proof that she had a disability and she could produce none. I asked her if she even knew what Muscular Dystrophy was, and she said in these exact words "it is like a bug that affects muscles or something". Defeated and under threat of being kicked out of the movie the woman moved and the man got his seat back. It ended well but dishonest people like that woman make me sick.
<bot>: A perfectly fine woman lied about having Muscular Dystrophy to steal a man with Cerebral Palsy's handicapped seat. I managed to get the man's seat back.
