Guy asked me out?

I'm sixteen, and yesterday one of my coworkers--who I've barely talked to--direct messaged me on Instagram, and followed up (30 minutes later) with a text asking me if he could take me out for a "bite to eat." I've never been asked out before, and this is kind of a weird question but does this mean that he thinks I'm attractive? And also is it weird that he asked me out since we barely know each other?
