Girl's Behavior

Flirty or friendly?

I work at a gym and I've become friendly with customers, one who, the other day was walking toward the front desk where I was, the whole time she was walking back, she was smiling at me. I looked at her because I noticed her from my side view but I looked back trying to play it cool. She was ultimately just asking for equipment but normally people don't smile that long it's just like a quick one and that's it. AM I reading too much into it or what? Another time she was walking with her friend pass my desk and turned backt to me and smiled, it wasn't like a flirty smile but still more than other customers would do I assume. For context, my first interaaction was when I helped her with an issue I made small talk with her helping her, but not anything too crazy, jsut asked how she liked the gym.
