Murphy USA

I just went to Murphy's and I was very upset. I have been going to Murphy's since they opened and have never been treated so badly. I was actually not allowed to get Gas or my sons milk because I didn't know my gas pump number. I told the guy that I had only came in because my Walmart gift card wouldn't work on the out side pump. (Which they say they will give you money off if you us it.) Then in front of me he gets on the loud speaker and says all customers need to know there pump number. I told him that that was not nice to do that in front of me and he said "Don't tell me what offends you and if you keep up the attitude I will refuse your service." I think that was rude! He said how much and and gave him the money, I gave him to much so he gave some of it back he didn't like the way I took it so he refused my service and gave it all back. He said if I don't leave he will call the police and have me arrested. I was with my young child. I will never go back to them every again! They have the worst service.
