If you mean in English, I would say look to the poorer corners of blighty, or deep enough into Australia, and you may find what you need. Or, if you're in Los Angeles and white, ride the bus from Santa Monica to DTLA on any given weekend and just listen to people talk: that's English just as sure as mine is, but I get maybe half.

(Also, is Scots not a dialect of English? I'm not sure -- a mix at the very least. Great tutorials on TikTok for that as it's apparently endangered.)

If you mean German, haha that's easy, just go to Switzerland with a short stop in Swabia on the way, though in both places you'll have to practically beg people to speak their native tongue in front of a foreigner. The Swiss Germans especially will reflexively speak one of the major foreign tongues, namely Hochdeutsch or English, though in my experience the Swabians will still say stuff like schaffe gell and assume you can grok it since Germans know that much from TV.
