Sunoco Gas Station

I have loved with Sunoco for years... Its the only place we really like to buy gas until today. While at the store today the employee DAHHANI treated a senior citizen with the utmost disrespect I have ever seen in my life. He had made a mistake on hi register and came out ad demanded the elderly gentleman to give him cash. the Elderly man didn't understand why he had to give the attendant cash and the attendant started raising his voice with the senior citizen. So the elderly man started shaking and handed over the cash and then got into his car thus paying for he attendants mistake. I then went in to argue with the clerk and refused pay for his mistake. I tried to explain to him that the customer should not have to pay more because he messed up so he started yelling then obv I did. Long story short be careful if dealing with this man. He will not correct his mistakes and hewill make customers pay for them. His is EXTREMELY RUDE and DISPECTFUL TO ELDERLY.
