So I understand portion control (in theory) and I'm not a germophobe, but...
Our workplace has shared food resources and a number of peculiar skinny ladies. They will pick up what is generally understood to be an individual discrete food object, awkwardly and imprecisely rip it into two pieces with their bare hands, then return one of the halves to the shared plate/tray/container.
I've seen this happen to a pizza slice, a banana, a cookie, a cupcake, and a licorice vine among other victims. Is this normal behavior?
