Lochcarron garage is shut on Sunday, so you wont be able to get fuel from there. They are open Monday to saturday 07:00 to 20:00hrs. The Spar shop has a 24 hour fuel pump if your desperate.
There is a cash machine at the Spar fuel station, but alas its not a free one I think its something like £1.80 to get cash out of it, so I don't use it. During opening hours you can get cash back from lochcarron garage and the post office based in the Spar shop offers banking services for quite a few banks.
