How to Catch Food Thief in Hall

Sorry for the stagnant blog as I was busy during work and stuff.... Haha anyway... how to catch thief in the hall you stay whom always steal ur food? One good way is to buy food that the thief steals often from the basket of stuff u got in Hall... then u add some laxative to it. After the food is gone... u pay attention who in the hall had diaherrea... the one who had it is the culprit and he or she deserve to stay in the toilet to clear his or her bowels LOL!
