I open girl over the shoulder with a false time constraint and then go into an opinion opener. She replies but this is the UK so she's a little bit weirded out about why a stranger is talking to her.

I follow up with her answer and use it to carry on talking and drop in some DHV's (story includes the leader of men angle and stuff)

She doesn't really respond much.

I test her compliance and tell her to join me at the bar but she says 'no thanks. I don't wanna give you the wrong idea. You're not my type''

I try to 'flip the script' and i'm like ''Let's not get carried away! Maybe you're not my type either'' (disqualifying myself) and smile then ramble a little

I need to respond to her lack of compliance with an IOD so I turn my body away from her a little and scan the room like she's lost my attention.

I can sense she's about to walk away so I quickly go into another DHV story.

She still isn't biting and tells me it was nice meeting me

Not sure why it didn't work/why she wasn't attracted? Where did I go wrong in that interaction?
