Have there been people who have already started, is it easy to operate ?

The buckle is there, just not very big, hidden on the side of the oil gun, and needs to be pried out.

Disposable gloves are provided at each gas station. Remember to wear gloves before refueling, otherwise your hands may smell of gasoline. Refueling is very convenient. After filling up by yourself, check the number of the oil gun position, and then go inside the convenience store to tell the number and pay the money.

Just now, I said that except for the TESCO gas station operation, even their employees are scratching their heads, otherwise it's very convenient. After filling up the gas, report the machine number and swipe the card. Don't forget to be polite before and after.

It's okay to refuel, but the fuel gun doesn't have a lock, so you have to keep holding it to refuel. When the tank is full, the fuel gun will pop, so make sure to note the number before paying.
