How do I ask a local for directions without sounding like an AI translator?

I’m visiting Sarajevo next month and I’m terrified of just blurting out stiff, formal textbook phrases. I want to sound natural, not like a tourist who just finished a Duolingo lesson. I've been experimenting with Chickytutor.com to simulate real-world scenarios and get feedback on my phrasing, but does anyone have tips on regional Bosnian slang I should know to blend in slightly better?
