What should I do if a guy left his number on my windshield?

Right after I pulled into a space a car parked in the spot next to me. I was with a friend and she was waiting for the guy in that car to get out so I just went ahead and got out of my car and waited for her, then as I was standing there he walked past me and I was pretty sure he checked me out but I brushed it off. As we were walking to the building she said he turned around several times and would check me out and when we finally got to the door he held it open for us. So we went shopping and I never really thought about it again until we were walking back the my car and I noticed his was no longer there. As we got in she said she thought he would leave a note so I glanced at my windshield and there was a note under the wiper on the passenger side, we got it and found a note that said 'From the guy in the car next to you, give me a call some time" with his #. Since the note was left on the side he was parked on and her side of the car does that mean it's for her,or that was just convenient? And should I text him and ask who it's for?
