How should I show this guy I'm interested?

I went into my Verizon store the other day and saw this really cute guy! He helped me for like an hour and a half trying to fix my phone. He was super nice (which might just be good customer service) but he also kept watching me when he was on the phone with the tech guy. We kept making eye contact and smiling. At the end, he was like, "well I guess that's it, unless I can do something else for you?" And then my son, who I was holding, totally poked me in the face and I was embarrassed lol and I said, "nope! That's it. Have a nice day" and I smiled and walked away lol did I miss my moment to make a suggestive move?
