I'm about to leave work for a new job and a manager has been flirting, but we hardly saw each other and had little time to talk and all the departments have security cards, so I had little opportunity to build rapport. She's given enough signals to convey interest. Of course approaching would be ideal, but if I don't get a chance to talk to her before I leave would it be totally lame if I leave a business card on her car with a note on the back that says something like "we didn't get a chance to talk. We should get coffee sometime"?

It's definitely not the best option. You want to be able to ask and get a response. I'm sure there's phones and email. Leaving a note on the car seems a little cowardly.

There's no company email or phone directory, at least none that anyone outside of scheduling would have access to. If I word it properly, it shouldn't sound like I'm too chickenshit to ask in person. Waiting at her car would be creepy, and the security cards make it hard for me to visit her office.

While you're at it make sure the name of your business on the card is printed out as "Female Body Inspector" and make sure you have the capital letters big in bold while all the other letters are way smaller lol

Just like JackZero said it does seem a little cowardly because it is

There are so many other ways and better ways to do this, but if you really don't have time to talk to her then you should say to her that you are both very busy there and you have enjoyed talking with her. Then TELL her she "should" give you her number so you can talk more when you both have some time.

This gives a great and valid reason as well... the lack of time.

I would wait and see what her reaction is when you say the first thing about enjoying talking with her because if she isn't enjoying it and doesn't agree and sound enthused then that could be a sign to let it go lol

Best luck man.

In the game no concept just build a rapport. Your target must be or sex or LTR. Without that you dont have a result. This is first.

Second, you dont have a much of confidence, its bad. You must be more courage.

Third, do not invite girl to date with question, its mistake. Better say: "I go to NAMEPLACE drink coffee, you can join to me at 19:00 its be pleasure to me".

DONT invite a girl with card - its right way to her fan, and never to a boyfriend, invite only directly.

This is superficially, you still needs to work and hard work on yourself.

Sorry, if my english not good.

Good Luck!

Extremely.

It's very lame.

Yep, there was no bite. Thing is, the girls I'd asked unanimously said if they'd been flirting with a guy a lot, they'd take the bait (that's the only reason I tried it at all, though I wasn't convinced it would work). There's no proof that she even saw it, though she most likely did. So at this point would it be worth dropping by and doing some shopping and see if she's receptive or avoids me (and if she's acting receptive ask her for the number)? Or it would most likely create an awkward situation and I'm better off forgetting it?

In case you're wondering what my reasoning was in the first place, I decided I'd rather do something that was a shot in the dark, cause if I did nothing at all I would've regretted it more than doing something lame. Because you learn from trying and failing, you don't learn anything from doing nothing.

I stopped by and it wasn't awkward at all. She was pretty unreactive when I said "hi", and nonchalantly said "hi" and kept going about her business, without slowing her pace or even looking. So I didn't bother. She's had a weird dynamic where she would be smiling and avoiding eye contact, occasionally do some suggestive body language, giggling when I say something funny to another coworker, staring and crossing paths a lot when I don't pay attention, on a rare occasion giving intense eye contact. But having a conversation was like pulling teeth, and she hardly said a word, and a lot of times would avoid eye contact altogether. Fuck. Well today was a last shot, and I'm done. I guess I can't take it personally. Maybe desperately shy or something.

Dude you left your business card on her car and she's desperately shy?

Also you listened to women giving advice on how to get women. Lol.
