For my script my path consists of stopping and paying a fare to continue the path,

How would one simply create multiple paths, in example: path to pay fare, pay it, then to the bank area

Position[] pathToBank = new Position[]{new Position(pos1), new Position(po2)};
Position[] pathToMining = new Position[]{new Position(pos3), new Position(po4)};

Paying the fare isn't handled as a path, that's an obstacle you must overcome, one way you could do it (very bad practice but works):

Area payFare = new Area(COORDS_OF_FARE_AREA);
if(payFare.contains(myPlayer())){
   payFare();
}
