It isn't that niche, and I think we should get annoyed by things that are factually wrong. I also get irritated when people say that Guildford has a cobbled High Street.
Most people won't care about either of these of course... or the London prefix to Gatwick Airport! :D
There is the whole width of a County between Gatwick and London. Makes no sense at all.
As it happens there are two railway stations in Guildford, 'Guildford' and, erm, 'London Road'.
I'm sure I'm not the only one who finds the creeping use of the Amercanism 'train station' annoying, it...
