I end up avoiding Shell station whenever possible because of their awful 'attended service'.
This basically means some guy tries to flog you a Shell Card (where you get a measly voucher after spending about £2k on petrol) and won't take no for answer. They're pushy as fook.
You are also forced to go into the
shop to pay whereas all you wanted to do use the self service card reader so you can be out of there as soon as possible.
Get with the times Shell. It's not the 1950's where people thought going to the petrol station was a novel experience. I want to be in and out ASAP.
