My pet hospital rant has nothing to do with food or low carb, but I find it, in hindsight, amusing. I had had a hard time sleeping, and when the nurse came in at 3 in the morning to take my vitals I was not happy - but compliant; I know they have a schedule to keep, and more work than a limited staff can accomplish easily (hospital staffing problem, not individuals being difficult). But when he then said that it was "time to pee" i got upset and said no, it wasn't; let me sleep. No, he had time then, and my output had to be measured. I said no, I can do that. His face was a picture: "But ... but ... it's in metric!" I am normally a fairly laid back person, and understanding of other people's issues, but at 3 in the morning, suffering from lack of sleep, I fear I was quite rude to the poor man. :-). And yes, later I was quite capable of measuring my own output, even though it was metric, and writing it down on the appropriate sheet of paper.
Of course, nowadays, 3 o'clock pee time sounds about right :-)
