Picture the scene.
You crack open the fridge, fumble past the leftovers and (hurrah!) locate that jar of mustard that you could have sworn was half-full. Only those deceptive splodges clinging to the sides of the jar are little more than a masquerade of thin smears and (boo!) the jar is, in fact, devoid of any appreciable content.
Where once there was mustard, now there is only disappointment.
Curses! Empty jar syndrome strikes again...
Whaddya Sayin’?
