ARCO Gas Stations complaint: Fraudulent transaction

I arrived at your location that frequent often on 12621 around 8:30pm. Due to problems at the pumps with scammers using card readers to obtain bank information I thought it best to walk in and use my debit card with the clerk at the register. I bought a 99cent fountain drink and i told the clerk to give me $40 on pump 3. My total debit charge was $41.46 gas and drink. As I approached my vehicle i realized i was on pump 5 an immediately turned around to let the clerk know I was actually on 5 and not 3 and because I didnt have my glasses on i couldn’t make out the number from inside the store. He then told me that unfortunately that someone had pumped the gas i paid for on pump 3 already and that was not the fault of the station but mine. However 3 was right on the other side of myself and no one was there and i would just move my car over and did! As i stood at pump 3 pressing it to activate the gas flow nothing happened and went back in to find out why it wasnt pumping gas and he told me he was sorry but someone had used the gas i paid for and i would have to pay additional money for gas. I asked for a manager because the clerk started getting loud and and cussing at me and I asked for a manager because of his actions. I explained my situation and showed him how my bank had been charged the $41.46 but i hadnt pumped any gas and this other guy was cussing and saying its my fault that someone stold my gas and there was nothing either one could do. The the first clerk told to return at 10pm so he could kick my ass because i accused him of trying to scam me. When i asked for the receipt I saw how the transaction was split? He put $20 on pump 3 i never used and did a $20 cash back that went in his pocket!. I called Wells Fargo to reportvthis and a fraud claim has been established but furthermore it it not right for under the influence store clerks to act as this person did or to threaten a customer. I contacted the Lakewood Sheriff’s dept to let them know as well but it ARCO who needs to better screen its hired employees and I will never set foot in another ARCO from this point on
