Metro by T-Mobile review: rude customer service from the employee

I went to the store about 12 or 1 pm, to get a car charger, I explain the employee that I see if there car charger that they have work in my car. So the employee got nervous so I told her to hold my credit card and i will be right now with the car charger in my hand to see if it actually fit in my car. So I continue to plug in the car charger connected to my iphone 11, to see if will connect i have to turn on my car, to see if my phone was charging. The employee came running out like i was gone steal the car charger, remind you that she has my credit card that she is holding . I personally felt that I was profile as a bad person because of the color of skin. I had on baggy clothes, sweatshirt and flip fop shoes, and my hair was not brush back in a pony tail. I am 37 African American Female that work in the healthcare industry never had no one judge me because what i had on. Yes i think the employee is a racist need to realize that you cant judge someone by what they are wearing, I might have been a corporate person for metro pcs trying to how is there custommer service in the store going.
