    Andy and employee at this location came out going off and yelling at me about did I see the sign did I see the sign over and over again them proceeded to tell me that semi trucks aren't allowed to get fuel. It is only allowed for trucks When I was in the process of getting fuel. I've been coming to this location for over 10 years and have never had an employee treat me rude or aggressive in any way. This is completely uncalled for. In that shouldn't have his job. There is no excuse for his actions or any of the excuses he tried speaking with his other management when I asked to speak to a manager about his behavior. I would like reprimands for his behavior if possible. But also will no longer be coming to this facility.
