You have to do something significantly bad to mess up your interaction or closing chances. This is something I've noticed with all of them; generally very warm and friendly, making you both more comfortable with each other, you can think clearer and the whole interaction becomes easier to effectively lead. And this doesn't just apply to tourists, but those who were born elsewhere and now live where you live.

To give you an example, I recently approached some girl who was studying some notes at a table, was in two minds because I didn't want to disturb her, but then randomly thought of asking where a shop was (pretending I had forgot the name), then quickly transitioned by saying "I notice you have an accent", then she said she was from Russia so I sat down and we talked before swapping numbers (I said I'd invite her out sometime soon). Thing is, my frame wasn't even very strong and I didn't really neg or DHV, but she stopped what she was doing, put her attention of the stranger being myself and was pleased with the idea of meeting again within a short time (I can always tell when people aren't fully sold on the idea but play along anyway). I know you might be thinking, well that's common for Day Game... but I've tried many times and Aussie girls usually aren't as responsive (harder to make them want to stay, talk and be interested).

yeah best tip if you meet someone foreign and you know one woord in their language it's a done deal.
