APlus Sunoco Station, [protected]), 519 Washington Street, Middletown, CT April 30, 2019, 19:19:57. I pressed the 87 octane button at the pump. When I started pumping my gas, I realized that the more expensive 93 octane button was lit up, not the 87 octane one. I ALWAYS choose 87, I KNOW I pressed it firmly, and this is NOT the first time this has happened at this Sunoco. This might be the sixth or so time this has happened. And it tends to happen when using my Price Chopper rewards card. I've never had this issue at other gas stations. Customers who aren't paying attention are purchasing more expensive gas when they think they're utilizing their rewards discount. The Sunoco cashier tried to tell me that I accidentally hit the 93 button with the nozzle, then he tried to convince me that I didn't select the gas and grab the nozzle in the proper order. This rip-off scam happens too frequently, so I will no longer be getting my gasoline at ANY Sunoco. I've heard others complain about this. This gas station needs to be investigated.
