Why this bank teller flirting with me?

Today I went to the bank to withdraw a lot of money and the bank teller asked me a lot of personal questions like - was a full time student? Were my glasses too big for me? Do I know who deposited the money to my account? Do I know why this mall keeps withdrawing money from my bank account every month etc? When he asked me about the glasses I felt like he was trying to get personal with me. Does he like me? I have an above average face but my body is below average and I'm presentable but a little awkward in the way I carry myself. I don't get hit on very often but that would be cool if he was hitting on me.
