My recollection is that when the first credit card bowsers were introduced at YLEC, they were Shell. AirBP doesn’t ‘do’ credit card bowsers - kinda one of the facts discussed in this thread.
Happy to stand corrected of course. As you say, DF will shed (authoritative) light on the subject.
PS added after reading DF’s. That confirms YLEC was never a BP credit card bowser. I will have to look at my CC statements for YLEC refuels to work out why I thought they were Shell bowsers.
