I pay using the Shell app, it’s great. Quick to use, and during these times of COVID-19 it removes a potential transmission route, ie paying at the kiosk or pay at pump.
Can’t understand the Shell thing, what’s the ‘need’ for such an app? Looks to be a bit long-winded to me, quicker just to use ‘pay at the pump’, you’ve got to get out of the car anyway.
I prefer paying at the pump. From what I've seen there is precious little chance of paying at the pump anymore in a Shell garage. All of the ones I've used recently have removed paying at the pump, so it's the phone app or a trip into the shop. I'm not a big mobile phone user and don't always carry it with me so Shell have made a backward step in some respects effectively saying you will do it our way and to hell with customer convenience. As a result I'll avoid Shell garages unless there is no option.
