<human>: I'm a shy, socially anxious person who is rather behind the times when it comes to dating, and have been trying to work on my self-esteem and get out of my comfort zone more often.

Visited a cafe yesterday with my family and noticed a pretty girl working there; we made eye contact several times and I tried to just smile without looking like a creep or an idiot.

We were there just before closing time, and as my family filed out I went over to her while she was sweeping up, said hi and tried to make small talk, turns out she's travelling around for a year and will be in my area for a while.

I smiled again said "Lovely to meet you" or something and left.

Afterward the idiocy sank in:

* Didn't introduce myself properly by name or ask for hers
* Didn't ask if she'd like to hang out sometime and/or for her number
* Didn't ask what days she works at the cafe

The cafe is in my local area. How do you suggest I go back there and try find out what days she works there, or - if she's there when I go back - talk to her again without coming across as creepy or an idiot?

Thank you.

Give me the gist of the text in a nutshell
<bot>: Forgot to ask for girl's number when talking to her first time, how do I go back to talk to her without being creepy
