should I send him a friend request?

[born_4the_beach18]

I ran into a guy from high school I hadn't seen in almost 7 years. He was never really friends with me but yesterday he was my waiter at a restaurant. He recognized me right away and knew the women I was having lunch with. He was like " yeah I went to high school with this one" and smiled. When I guessed his name right he was like " yes ma'am" with a flirty smile. He asked the other ladies with me what they wanted but when it came to me he just looked me in the eyes without saying anything. He checked on our table more than he did any other table. He looked over at me a lot from across the room especially when he was talking to another girl. He checked me out a few times.When he brought our check he turned to leave then turned back to me and said it was nice seeing me again before he turned and walked away. As I was leaving I could feel him checking me out. Was he interested in me? Should I find him on Facebook?
