OK food market treat customers as *****s!

Went to Willows OK mini market to buy a couple of things this morning (03 Feb 2019), was told to leave my small purse in the locker as I'm not allowed to enter the store with it. My question was, should I now shop around with money and cards in my hands just because I want to buy from their store?. The manager ir floor manager came and insisted I should leave my essential personal belongings in the locker as my purse is not allowed in their store. Are these people for real?. I immediately left the store as what I was asked to do was insane. Why should I suddenly be treated as a ***** just because I decided to buy at OK. This is not acceptable, I demand and apology and this paranoia bad customer treatment behavior must fall!.
