Treated like a ********-Disgusted

The so called checker at the door made me feel like a ********/shoplifter when I went to buy groceries at Kit Kat Cash and Carry in Benoni . I understand that they must check the receipt against the items bought, but this guy literally took out everything item from my trolley to ensure that I did not ***** it. We were not allowed to leave as he could not find the entry for two packets of beans that was bought. If he had looked properly, he could have seen earlier that it was on the top half of the till slip. they need to do something about this or come up with a better way to check if items were paid for.
