Is it weird to add someone on facebook using the 'workplace' search if you just met that person once?

So in whole foods today, I met this girl who I got good vibes from. We talked for a couple minutes and she mentioned she works security at the natural history museum. I just found her facebook profile by searching her name and adding where she worked. Should I friend her? Is it too weird that I searched for her, not knowing her last name but where she worked?
