Need help with 'rexeitar' and common vocabulary traps for a trip to A Coruña

I'm a traveler visiting Galicia for two weeks and I want to avoid sounding like a tourist who just translated Spanish into Galician word-for-word. I keep running into 'false friends' with vocabulary. Does anyone have a list of hyper-local, practical phrases that locals in A Coruña actually use? I want to avoid the app-based vocabulary which feels a bit too formal or Castilian-influenced for daily life.
