Get your money ( sterling) out of the bank atm,ie the one outside the bank,not a remote one.Take it inside with your passport and exchange it.Thats the best deal.unfortunately most atms,do not dispense sterling.In calis its hsbc near the water taxi bridge,or hsbc in fethiye,both at the bank and in front of the PTT (post office)If you are coming into town from gunlukbasi, use the TEB branch just down from Carrefore exspress.But the main TEB atm in fethiye does not carry sterling.hope this helps.
