Guys, would you kiss a girl if you weren't interested in her?

I was pretty sure this guy wasn't interested on our date but I thought I would go for it anyway and he kissed me back with tongues for about 20 mins. But I have not heard from him since. Would he still have kissed me even if he wasn't interested?

We're not teens, I'm 24, he's 26. We were on a date and the kiss was at the train station as we were leaving. (If this makes any difference to the answers, lol)
