I live in the cousin-fuckingly deep US south, and this is something that REALLY triggers the local rednecks.
One of the funniest things I've seen since moving here was at a local grocery store - a self-checkout kiosk got set to a British accent, and the workers either didn't know how or didn't care enough to change it back, so it just stayed like that for a month or so.
Every single time I went to the store during that period, I'd hear some dumbass hick say something along the lines of "...can't even buy fuckin potatoes anymore without having to listen to some commie bullshit."
They absolutely hated it. Like red-in-the-face, day-ruined hated it. It was amazing.
