The exact same words and tonality and everything would have 'worked' in a different situation. It's almost never ever a 'game' issue
In this situation it's a mixture of
1/ just a lack of attraction. I didn't watch the whole vid but the guy is described as a '4'. So makes sense
2/ Location. Looks to be the UK. People who don't live here don't seem to realise that outside of maybe central London (where PUA's film due to knowing that tourists are more receptive), or possibly places up North like Newcastle, talking to strangers just isn't really a thing here. It's worlds apart from America in that sense. The confused, suspicious look of contempt on her face is just classic! lol. She's screaming 'why are you talking to me? I don't know you! This is weird!!' in her head (which funnily enough is almost exactly what a girl said to my wingman the other night when he approached!)
Even if that dude was a fair bit better looking, there'd still be fairly decent odds it would have played out exactly the same. It's why i've always said that cold approach (particularly here) is literally just a game of trying to find the gilrs who think you are hot, AND who also happen to be unusually friend/sociable with strangers. Hence you need to put in some serious numbers in order to get lucky!
The dating company 'love systems' made a really long, detailed post about the difference between game in the US and the UK from the perspective of their various dating coaches once. I remember agreeing with most of it. One of the things was something lke (paraphrased) how walking up too a girl and saying 'hi, i'm gary' too a girl in America would likely get a smile and a reply of 'Hi! I'm Sarah! Nice to meet you'. Whereas in the UK, if you walk up too a girl and say 'hi, I'm Gary', she would be a mixture of confused, scared, suspicious. She would possible say 'Errr....OK? and walk away. No way is she gonna volunteer her name and encourage further communication. She'd think you were maybe very unusual/odd or possibly trying to sell her something
