The Five-second Rule Applies
Behind the closed doors of the kitchen, anything goes. Under the gun for time and trying to keep a hundred strangers from going hungry, it gets tempting to cut a few corners if no one is looking. Granted, we're not talking about rescuing a gloppy lump of bleu cheese that fell into the sink, but chicken cutlets hit the countertop, cutlery gets rescued from the floor, and the occasional thumb accidentally dips into the soup on the way out into the dining area.
But it takes five seconds for food that falls on the floor to get really germy, right? Right? Maybe just a quick rinse in the sink if nobody saw anything ...
