Humiliated

Yesterday I went to woolworths maponya Mall, to shop for snacks and drinks, when I was done with my shopping leaving the store the security guard at the door place his leg in front on those alarm things at the entrance same time was I was about to exit the door and it beeped and he stop me, to search my items, he only searched to items, did not check the slip, did not if check those items at that alarm thing if these items had tags, funny thing it's snacks, I felt so humiliated as if was the theive, or is the the problem that I come every week to shop the or is it the way I dressed but like really I'm really disappointed, came back the second time, same day cause my app had issues to I went to the bank to fix it and purchased those items I left back, still I had a security guard following me as if I was the only person who was shopping in that store, even now I can't sleep thinking how I was treated at woolworths, funny thing I shop there peacefully, I buy with cash I don't bother anyone, but being humiliated like that it's other thing,
