I think she likes me?

Long story short when we lock eyes (it’s often) we always smile at each other and I’ve made her blush and smile and laugh.. One point I didn’t know she was behind me when I got into my vehicle and she turned to look at me and wave and I waved back. So now today I asked her what she was doing next and she was going to her family restaurant to help out and she asked me when I got off work (I think this one flew over my head) during this time she was smiling but when I told her before she left I’m going to miss her smile her smile got extra big and she started fanning her face.

That’s the part that confuses me a big what is fanning her face supposed to mean? I already knew she was blushing. I told her I would see her tomorrow.. but I wonder if it would be too much and too fast if I would check out her family restaurant or if it would be appropriate to flirt even more at that time.. but even more it seems like she’s interested should I wait to give my number or do it now?
