Stop in for a cup of coffee

so... if you don't sign out what then - how stupid is that!!? F you and your bill, let me out of here - NOW!
My work place made me go see the DR. and it just went from there. My dr wasn't in and the one standing in send me to the emergency room and I have to prove I was at the Dr. to get back into work. So yes if I signed out against their consent I was told that my insurance would not pay for anything to this point. It was crazy.
