Hey, need some advice. I went out Friday night, and had what I felt was some pretty good game. I got this girl that everybody else was trying to dance with to dance with me... and she didn't dance with anybody else except a female friend all night. She was all over me, hard enough that she dyed the front of my jeans pink from her red dress

.
I managed to escalate to some pretty heavy petting, but wasn't able to kiss close before the club closed. Outside I was trying to get her to come to an after party with me, however her friend was physically dragging her off. I managed to number close, but either she gave me a wrong number or I took it down wrong because I was drunk and she was hard to hear. She seemed genuinely interested, and really didn't want to leave with her friend (tried to come back but got dragged off).
I found out where she works, and was wondering if it was a good idea to go there to see if I can try for a day 2. I was thinking along the lines of "looking for a birthday gift" as she works in a women's clothing store.
Any advice, or just drop it and move to the next one?
