Today's OneWord: Groceries

I unpacked the groceries only to find a silver pocket watch lodged between the loaf of bread and the jar of marinara sauce. I looked at it curiously. How in the world had it ended up in the paper bag? Had someone accidentally dropped it while passing my cart? No - it had to have been purposeful. A gentleman had jostled me slightly on my way out of the store. Whatever his intention was of leaving me this watch - if it had been him, of course - was beyond me.
