Comment: You do not recover from norovirus in one day!  It took me five days once to get over it and that's about average.    This is not food poisoning. Don't confuse the two.   This didn't come from spoiled food.  This came from food handlers who didn't wash their hands after pooping.  Gross and disgusting.  You can sanitize the place all you want, but if the person handling you food didn't wash their hands....you're screwed.
