Unacceptable horrible unprofessional manners

We were busy shopping at around 5:45 to 6pm then an old lady approached us and said can what can I help you with ? We are closed And I want to mop the floor and I responded by saying , we still shopping. She took the mop then started mopping my feet and started mourning with her colleagues in their own codes of languages saying it's late and they tired they want to go home. I asked them to open the door because we were not welcomed to shop with them and I asked the security guy, why are they taking their time to open for us because they chased us out and asked for that old lady's name but they refused to give until this other lady came and tell us that is Emily. We were terrified and believe me it was Shocking, How can someone give a horrible service like that? Mopping a customer's feet? They should have said that the store closes at 5:45pm Not 6pm. Horrible terrible customer service I've ever experienced in my whole entire life. ....
