ARCO review: a mean owner lady

Hi my name is Sassy and i was at Arco station on Wednesday May 28th around 12:30pm. I got cup of soda and employee charged me wrong price. The owner she was there and she yelled at the him. I felt very uneasy. I even told her it's ok you can charge me whatever right price is and then she told me it's none of your business. I don't understand what kind workplace is this for employees and what kind customer service is this. I just like to file this complaint that lady has to know how to talk to people. I don't think that lady is normal.
