Kroger

I look on an app yesterday called Flipp, it has ads from all nearby stores. The Kroger ad had in store sale for Dr Pepper/Pepsi 6 packs 10 for 10.00, so I went to go my mom some. I asked a cashier and he acted like he didn't know nothing so i asked for a manager. This man was so damn rude and disrespectful towards me. Saying he didn't know anything about the ad. I was trying to show him on my phone and he took my phone out of my hand and started scrolling through it. I was about to start cussing him out at this point. He walked out my face SEVERAL TIMES while i was talking to him like i was nothing. I saw him being nice to others in the store so I believe I was disrespected because of my dark skin tone. I told him i was going to call Kroger's Corp ofc, he said go ahead, I don't care. He was totally disrespecting me in front of customers. I'm a grown woman, 56 yrs old and I WILL NOT BE SPOKEN TO AS IF I AM HIS SLAVE OR HOUSEKEEPER. I will no longer shop at Kroger, I will also tell family and Facebook friends not to shop your stores because people of color will be disrespected
