Well as a Costco gas employee what we do there is actually activate and operate all the gas pumps and make sure everything is running smoothly , no one tampers with them and keeps you info safe and secure , assist with guests who’s membership cards don’t work (happens very often)
Then there’s the gas fill ups from tankers that Costco employees only have to operate not the driver , spills and or injuries ...without employees there the Costco gas can not function
