Should I double text?

So I met this guy when he was working at Starbucks yesterday. I got his number (he typed it in my phone himself and called his phone from my phone so he’d have my number as well). Later on that day I hung out with my friends and saw a school play so I didn’t text him right away. I waited till noon today and I texted him saying hey this is blah blah blah we met yesterday. He hasn’t responded and he’s mad cute so idk if I should double text or just wait a couple of days. Any ideas?
