The chance of her not asking if I want the receipt, is very small. Literally 9 out of 10 times, they do ask for it. Still, if she doesn't ask, I'll simply wait until the next time.
If she just laughs and gives me the receipt without her number, I'll be persistent. I won't take the receipt from her, I'll just stare at the receipt while she holds it out and say: "Well...where's the number?" Of course I'll do this in a very playful way.
Anyway... The idea I came up with, as well as any out of the blue "Hey, I wanna take you out, give me your number" (or anything of the likes), doesn't seem good enough to me. I think it's essential to make her laugh or get her to "open up" in any other way. They're basically robots, they're just repeating the same process over and over: *bleep*, *bleep*, "That'll be blah blah Euro and blah blah cents...Have a nice day!" Now some of em still manage to make real contact with their customers and focussed on their surroundings, but others tend to turn inwards and just consider every customer as sort of a number. They make eye contact and talk to you but they don't really "see" you, you might as well be one of the products that she *bleeps*... Well, the girl I'm interested in seems to be of this last kind... I need to open her up before I make a move.
So I feel I need to make a joke or at least do a little chit chat with her, before I go for her number. To be honest, I think situational openers work best for me. I have to come up with something there and then, I tend to f*ck up when I decide what to say beforehand. But any suggestions are welcome, guys!
Jitterbug, I've been thinking about that too. Just establishing rapport a little bit with every encounter... I'm just worried it'll become obvious and I'll seem stupid. Like she'll notice that I'm always checking out at her cash register and not at the others. Also, she'll notice that I'm always trying to do small talk with her. I'm afraid she might start to think: "Oh, here's THIS guy again...let's see which line he picks....yup, mine, what a surprise...now here he comes, I wonder if he'll make an attempt at small talk to me...yup, here he goes again...lol this guy is so predictable..." Know what I mean? It reminds me of when I was a small boy and had a crush on this girl from my class. I'd "accidentally" drive by her house very frequently...
That's why I think I should make a fast and decisive move. Actually, I'm already f*cking this thing up... I was there yesterday (before I started this thread) and even though I didn't do anything, I just know she could sense something was off about me, like I'm interested in her but I don't know what to say. I think I'm gonna totally neglect her until I have the right mood (****y, playful, not giving a damn) and then I'll just make one decisive move.
