Yeah bro, what everyone else has said.
She has made it very clear to you that she doesn't want to see you.
Accept that and move on. Don't take it personally. It's just punting.
If you like the shop you can go back and see different girls but avoid this girl.
If you think going back there is going to create issues for you then find another shop.
Sydney is a big city, plenty of shops, plenty of girls.
