My uncle was a sales rep travelling the Highlands for a while. His bosses had great difficulty grasping how long it was going to take him to get from prospect to prospect, because if you glanced at a map and assumed he could go more or less as the crow flies, it didn't look too bad, but of course you can't go as the crow flies. Mountains, winding roads, hairpin bends, single track roads with passing places, etc etc.
Indeed. This reminds me of a thread from a while ago where the OP had been given an experience-type voucher by a family member, but she lived deep in the Highlands - with young DC iirc - and the nearest place she could go for it was in Edinburgh.
It seems to be par for the course that, when things are sold/advertised as having lots of centres around the UK, and so promising that there will be one 'local to you', you'll find that they have 60 centres throughout England, one in Glasgow or Edinburgh, one in Cardiff or Newport and likely none at all in NI.
Nobody would dream of giving somebody in Newcastle a voucher for afternoon tea or paintballing in Exeter ("We checked - they do have a centre in England!") but Scotland is just one little local parish where everybody knows each other.
