I mainly read 'seddit' and generally people advise against trying to pickup girls who are at work since they're paid to be nice to you, plus it can make things awkward if it's somewhere you regularly go.
But there is this new pretty girl who works behind the bar of one of my regular pubs.
Is it worth approaching her? If so, how?
Am I supposed to just make usual small talk and ask her how her shift is going and stuff and then ask her more personal questions about what she does for fun ot something so that she at least knows who I am, and then maybe a few weeks down the line add her on facebook or ask her out or something?
Or am I supposed to just go up too her out of the blue whilst ordering a beer and just tell her I think she's cute and ask if she is single or something and 'go for it' straight away?
Here is my take on it
She is used to getting hit on all the time. She has probably heard it all, it almost does not matter what you say because chances are she will see right through your intentions. This means you will have to be different.
You need to get her to notice you. Usually this means playing the " long game" meaning its going to take a few visits to this pub. This is why I advice against picking up people in the service industry but if you still want to here is an example of something you can do.
You need to spark her curiosity. Sit at the bar alone and bring a book, something that is out of the ordinary. It helps if its something that you actually have knowledge in ( Who brings a book to a bar right?) Don't pay her much attention because I'm sure if she is attractive she is used to guys drooling over her. At this point your work or whatever you are doing is more important.
Eventually what you are doing will spark her curiosity, she will ask about what you are working on/ reading etc. You can take funny guy approach and say something outlandish to make her laugh. ( " I'm reading a book on how drinking is now proven to make you drive better") Be creative.
Don't continue small talk, stick to your work. After a drink or two ask for her name to thank her, then leave the pub.
Repeat this process with multiple visits, she will start to remember you because this type of behavior is not that common.
This is you separating yourself from the rest. (If this pub is casual , maybe dress up a little as well. This will help her remember you.)
With each visit you can talk/flirt more and more. You will get to know each other but it won't seem like you are there to see her. You are there because you have something to do.
Eventually her guard will go down and you can finally ask her out somewhere without getting some BS excuse.
