On a slightly related note: New waitress in an old restaurant in my town was clearly into me hard, to the point where she was forgetting how to talk or even take my order, just sit there staring at me and stuff. Super hot little thing. Me? Married. Sorry.
I overheard the waitresses talking all together at a table around that time and they were trying to tell the younger guy there about a certain type of confidence/sureness that is super attractive in men. He did not understand what they were talking about whatsoever.
Yeah, when you are married, you could care less about what the women you are talking to you think about you. Not nervous at all, why would I be?
Well, I get a lot more attention from women now, I think partially due to that.
Once I came in with my wife a bit later, the waitress was visibly saddened.
I mean, I have a tattoo on my ring finger of her name and wear a ring half the time, did not lead her on at all.
Just engaged in normal, confident, polite conversation, and she was all about it.
If she seems to be giving you any signs/signaling back, you gotta give it a shot!
