It's not just accents that vary, vocabulary can vary in 'interesting' ways.
In Fort William I was warned that if someone asked where I was staying, they didn't mean 'Are you staying in the Glen Nevis camp site or the hotel?' They meant 'Where do you live?'
When I went to the top of Ben Nevis (it was a few years ago, now) there was a group of fireman from Bolton at the top. I think they were being sponsored in aid of something. They were speculating about the purpose of the little hut, and eventually one of them went over to investigate. He reported that: 'It says "Refuge". It's for putting your rubbish in.'
