its true, i work at subway.
the double choclate usually break by themselves by the end of the night so i eat those, or i get impatient and just break them myself.    but you have to break of a quarter of it and put it into the box underneath the counter because the manager will count all the broken pieces including any bread.  so when he counts a piece it is counted as one, but i still get to eat the cookie so no one gets in trouble.
