I had to go buy my hair stuff which is super expensive $15 a bottle just for styler. While I was getting checked out the cashier was yelling across the store, literally, at her friend trying to figure out who was pregnant. Well she wasn't paying attention to what she was doing & didnt scan my hair stuff. I tried to stop her but when she realized that the customer was talking to her she scanned my Gatorade twice. I tried correcting her telling her no it was my hair stuff she looked at me like I was the one being rude & said "what". I laughed & said "nothing". Before I left I turned to her & said "you need to learn how to do your job because you suck & very rude, thanks for the hair stuff." & left
