Hey,
In each of the following approaches I used my usual opener. I ask the girl if she works in the airport in English. (They usually don’t understand- I live in Spain) and then ask in Spanish, their mother tongue, with a smile on my face.
I had a few hours to kill today so off I went to the mall. I went first to a newsagent.

Approach 1.
There was this pretty chic. She had a few pounds too many around the waist but what the fuck. I did my usual opener and it didn’t stick. So, I stuck around in the newsagent for a few more minutes, then left.

Approach 2.
Then I hit the supermarket, there is a section for books and so I hung around there. This girl appeared over at the video selection. So, I kinda walk over. I run my opener. She has a little laugh and moseys on. I don't try to continue.

Approach 3. Walking target.
I am in the supermarket still. I have an Asian looking chic coming towards me. I run the opener but barely get any response.

At this point, I have to get my head around this and so I go for a five minute break. I pop to a nearby beach and sit down for a while.
After this short recess I go back to the newsagents that I started off in. I see a babe and she is perhaps five metres. She gets nearer and nearer and stands next to me for a while. There is no one else in the shop. I mentally talk myself out of doing the approach based on the results from the previous 3 approaches.
Seconds later, i am wondering to myself if the staff in the shop are going to wise up to my popping into the shop twice in an hour and suddenly out of nowhere this babe HB9. asks me with a nice smile on her face “Hello, do you work here?”
I am dressed in jeans, a white t shirt and adidas black and white trainers. This is curiously exactly what happens to the guy in the film “better off dead” with Steve Carell, for anyone imagining the scenario and has seen the film. But he is wiser than I. He lies and says, he does work there and helps her to find a few books and bounces to a coffee shop.
I smile, say hi and then say no I don’t work here and leave.

Approach 4. I am in the supermarket again and there is this girl. I here try to use my head to segway off from the opener. So, the babe gets nearer to me and boom. Do you work in the airport?
Her. No. Well I must have someone who looks like me.
Me. You got a sister who works there.
Her. Giggling. No!!!!
Me. Well they say everyone has got a double somewhere in the world.. ..
I had pretty much zero approach anxiety. From this viewpoint I feel happy but on the other hand my conversational skills leave a lot to be desired.
Cheers guys.
