M Gas and Service Station

This gas station charges 10 to 15 cents extra for each gallon of gas purchased with a credit or debit card. Yes, I know credit card companies charge merchants a small percentage fee for transactions. However, charging extra for debit cards is a ripoff as processing them does not cost them anything.
Also, one of the gas attendants attempted to intimidate my father by reaching through the window and grabbing the steering wheel after my father refused to move the car up to a different pump since he had already turned it off. There was no one else at the station and the pump did work, so the demand was unnecessary and the attendant certainly didn’t have to react in a physical and threatening manner.
