I thought your story was rather interesting.  It appears to me that you slipped and fell and then posted some nasty comments on facebook about your experience.  This then triggered a number of nasty comments in response.  So perhaps the message here is A) maybe read a book in the waiting room rather than posting comments on facebook and B) if you feel the need to post something making idle threats is probably not the way to go.  

Lets all be nice and polite!
