Is this a sign she was flirting?

So yesterday was my birthday and k went to treat myself since all my friends were busy with Christmas stuff. At the place I went to, one of the workers and I started a conversation. She asked how old I was and I said it was my birthday. We talked some more and she asked if I had girlfriend. I told her no and a little bit of my breakup from a year ago. Before I left, she came to me with a coffee mug full of candy and a box of chocolate cherry cordials and said “ Happy Birthday and Merry Christmas.” I told her thank you and got her name.

I am wondering if she was flirting with me at the end. Because they weren’t giving those out to other people. I feel like she was give those and then she gave them to me. But I’m not sure if she was flirting, just being nice, or she didn’t want the gifts and was trying to get rid of them. Thoughts anyone?
