So I was riding with my cousin to Tokyo express, I just ate so I was just getting him something. Well as soon as I walked in the girl behind the register said "Oh hey" like she was pretty excited to see me or something, they weren't really busy so it was pretty much just me and her. This was the second time I've seen her before, the first time I only saw her for like 5 minutes cause I was in a hurry and they were pretty busy, we didn't really talk much the first time. This time we were kind of just making casual conversation while I was waiting, she was talking more than I was tho, and every time she said something to me she looked directly in my eyes and had this pretty big smile on her face. Then when the food was ready and I was about to leave she gave me the food, I looked at her and said "Thank you" and she said "you're welcome" with a big smile on her face, then we both just kind of stood there and were just looking each other in the eyes for a second, while she still had a pretty big smile on her face. It felt like she was kinda waiting for me to ask her out or something, but like an idiot I got nervous and said "You have a good night", she said "You too" and I left. Now I feel like an idiot because she was obviously somewhat attracted to me, and I didn't even ask her for her name or her number. I'm terrible at this, meeting new people and getting to know them without feeling like I'm annoying them or coming off as a creep or something. Once I get their name and number it's usually always ok, it's just the first initial approach that I always have trouble with, I'm just not sure exactly what to say or how to word it right without coming off the wrong way or something. She is incredibly beautiful and seemed somewhat flirty with me, she looks a lil older than me (which I don't mind) but I'm not sure how old she is. But what should I say? Please help.
