It is an awkward situation. I'd probably feel weird too. But also doesn't seem like a big deal. Especially in the end. Though it's a little odd phrasing of what he said in my opinion. "if you ever need anything let me know.". If you didn't think it was weird though, never mind. Why do you think you felt so uncomfortable? Was it because he asked your name? I understand feeling uncomfortable. One time, i volunteered at a nursing home and took some pictures of a halloween party and the residents. A nurse chastised me because i wasnt supposed to do that. A privacy issue. I apologized and erased the pics. It was awkward but i got over it. It sounds to me like you handled it fine by the way. . No worries.
