Metro by T-Mobile

Hello, I came into the store # 1275 in moorestown mall, NJ. The store was closed at 4pm on a Wednesday. (7/10/19) . I asked around if the store was open or undergoing construction and a store next to the metro said she was on her break, or wandering the mall. I waited for 20 minutes and she came in with her uniform shirt in a belly shirt tied behind her back and I said "excuse me I need to buy a phone." And she replied rudely and said "um I'm on my break." Another 15 minutes are going by and she's still on her break. I asked her name and she said Maria, and the same person I asked about her whereabouts says she does this a lot. And she wanders the mall frequently.
