Dude, look...I'm sure it's to find someone decent looking who shares your fandom and hey, isn't an asshole or a fangirl/fanboy or delusional or something along those lines.
But, hey...if I'm standing at the counter waiting to be rung up, stop the Romeo act for one second and please do your job. If she's interested in you as well, she'll wait. If she leaves, you're better off without her. Trust me on this one.
Thank you,
