CVS review: the manager black lady

I am in line and there is 3 people in front of me and this manager so she said she is black lady. With such a rude attitude. She opens another register and treats the two ladies in front of me rude going back and forth between registrars and telling customers that that's why they like her there because she multi tasks and she makes 6 digit figures. I honestly don't understand why she needs to so rude to the people and making comments... I will never shop at this store again... such bad customer service! No need for extra comments. MY receipt says Beatrice that's the rudest customer service I have wver
