Tesco's cheap petrol offer fails to impress Scottish islanders For motorists in Kirkwall, the ferry across the Pentland Firth, is a modest £94. But they will have to drive around 20 miles to pick up the boat in the first place. Not surprisingly island shoppers were unimpressed by the offer. People are treating it as a bit of joke. I don't think Tesco will create too many petrol tourists here," said Stornoway shopper Marion Macleod. They should open a petrol station here and bring cheap fuel to the islands - and then we can use these otherwise useless vouchers. Angus Nicolson, an accountant from Stornoway, added: "This has caused a fair bit of amusement locally. Given the costs involved of reaching the nearest mainland Tesco filling station, the company would have to pay islanders to fill-up to make it worthwhile. Only then would every little would help. A Tesco spokesman said: "We were offering this petrol promotion across the UK under exactly the same terms, which we think is a fair approach."
