Why would a waitress giggle at things I say that isn't funny?

She giggled at the fact I asked how she is. Only because she said hello how are you to me. Then I said "I'm good, how are you?". She even knows my coffee off by heart and she even knows where I work. I've only worn my work on the odd occasion there.
