The kid is trying to pull a heist-obviously-but he is evidently somewhere in Northern Germany,where many people's native tongue is Niedersachsisch or Low German.It is Low because the area is a coastal plain.
Standard German is Hochdeutsch-High because it is from Southern Germany,where the mountains are.
Low German languages didn't participate in some of the sound shifts that occurred in High German,so they sound different-sort of like an intermediate language between German and English.More like German,but still different.
The lady is asking him if he wants large or small bills,and paper or plastic to carry it with-I think.
A native speaker can correct me.
I don't catch much of what the cop is saying-likely something about putting the gun down.
Calls the kid something like "dirtbag" after they gun him down.
Anyone that's fluent,could you please translate the conversation?
