Yes.  I work as a registered nurse in a hospital.  I have so, so many stories about this. One fat idiot had to be NPO (nil per os, literally meaning "nothing by mouth") prior to a certain test. You usually only have to be NPO for 6 hours for most tests, but for this fatass that was too long apparantly and he decided to eat some food that he had hidden in his room. He was caught eating and told we would have to reschedule the test for tomorrow and he would have to be NPO again tomorrow.  He threw a fucking fit.  It was pathetic.  T  7fea  he guy looked like he was 50 but was acting like a 12 year old.  6 fucking hours, it's not like it's god damn Ramadan or something. Another fat moron had really bad respiratory failure and had to be put on an oxygen mask.  He kept taking it off to eat and then his oxygen would plummet.  We told him to stop doing that and he told us he was going to "starve to death". The guy weighed AT LEAST 450lbs, there was no way in hell he was going to starve any time soon.    I have more stories but this post is getting too long.
