Would you consider this stalking?

I work at a city hall. About 1 1/2 weeks ago a customer sent me flowers with a note that says “hi (my name) I’ve seen you are the city hall and thought you were pretty and you’ve helped me a couple time. If you want to grab a drink sometime call me” with his name and number. I didn’t recognize the name and after searching social media and seeing him I don’t recognize the face either. I ignored it and didn’t respond. 2 days ago he showed up at work, smiling and staring at me. Pretended to need something only I wasn’t the one who helped him. The girl who did knows who he is. Today he called twice asking for me, once saying he thought someone from the city called him and then again and left me a voicemail asking me out and if I’m married. I sent it to my boss who’s the building official and he called him and asked him to leave his staff alone. Then my husband called and told him to move on. Is this stalking? I literally don’t recognize him or remember helping him.
