He still remembers me?

I was at a hair salon getting my hair cut by a gorgeous guy and I had a feeling he was flirting with me. We made small talk, but it wasn't really something so big that a person would remember it. However, 6 months later, when I went back to the salon, he told me he still remembers me. When a guy remembers you, could it be that the girl left an impression on him or could it be that he just has really good memory?
