Sunoco review: rude & disrespectful

I have been a daily customer at this station and everytime I would go in when the manager is there, she is doesnt greet any customers, also, very rude and disrespectful. I have heard many times from her employees that shes the worst person to work for and that she treats her employees like she treats customers. Please I hope we can resolve this major issue. Thank you, , Sherri
