I just missed a chance to talk to a gorgeous woman, easily a 9/10 and exactly my type, a very rare encounter for me.

I've never gone out of my way for day game and cold approaches I'd like to get better at it but situations like this where she ticks all the boxes, FOMO kicks in and all my worries about what to say are overcome by the need to just say something but here was the issue:

She was behind me in line at a 7eleven. I only noticed her at a glance as I was walking out, by the time I did a double take and REALLY noticed her I was already outside and the automatic doors were already closing behind me.

I that situation is it just a fault of bad circumstance and move on with my life, or is there a way I couldve cold approached without coming off like a creep who clearly waited outside to talk to her?
