Do you give your number out if someone asks you in public?

I went to wash my car yesterday and while I was cleaning my car mats some guy helped me get them out of the machine. We started talking and he was very mellow and funny. I don't know how but he made me feel comfortable, he asked for my number and I gave it to him. He texted first and I don't know why but I’m getting so shy. This isn’t something I normally do.
