Shell Coles Express

It feels odd reviewing a petrol station but I had to do it given my experience is roughly the same every time I come here or any other Shell Service Station for that matter.
After I fill up I wander inside and the conversation generally goes like this;
Me, «Just the petrol on pump two thanks»
Attendant, «Would you like to buy some chocolates — they’re 3 for $ 5»
Me, «Just the petrol on pump two thanks»
Attendant, «Would you like a drink — we have 2 600ml cokes for $ 5»
Me, «Just the petrol on pump two thanks»
Attendant, «Do you have flybuys»
Me, «Just the petrol on pump two thanks»
Attendant, «How about some shop a dockets»
Me, «Just the petrol on pump two thanks»
And then I finally get to pay for the fuel! I don’t understand how Shell have not yet realised all they do is piss people off by trying to sell them everything when all they want to do is pay for their fuel. If they introduced a pay at the pump system I’d revise my rating to a 5!
