How effective is checking bought items at the door by ur stupid securities??

I wouldn't have written this if the security lady at the door did not make me look for orbits specifically among the lot of goods i purchased at your montague gardens store today. Now when i get home out of 4 boxes of orbits i got 3. I have no idea what happened to the other box from the till into the plastic. The lady security should have rather helped me know what happened to the other box instead of doing the opposite of what u want them to to on that door which i believe is to check if u did not smuggle unpaid items. The lady consumed my time after i've been walking long shopping asking me to take some items out so she can check the items she wanted to see and i was not rude or objected but now am ****ed cause what she was doing was not helping me. So tell me how effective is the checking my thousand worth of items packed in plastics at ur doors.
