This letter to the editor of the Irish Independent claims that a B & B in Donegal refused the custom of an American family because, supposedly, the owner of the B & B said he was "no longer taking booking from Americans" because "they often don't bother turning up". Could this even be vaguely true? Are Americans more likely to not turn up than other people? I'd be pretty skeptical about that.
Despite all the political tension over the past few years, I haven't heard any stories of this spilling over into the treatment that Americans receive here. I presume this, if true, is an isolated incident and not an indication that Americans may start receiving a frosty reception in Ireland.
