Was this his weird way of flirting?

Iv been working at a store for a while now. I would say I’m a cute girl and I always get complimented on something. I’ve gotten a lot of compliments on my face but I don’t rlly get hit on or anything:
Today there was this Latin guy who came in and was super nice and smiling and he told me he liked my nails. Then he was smiling and like “I always see you in here everytime I come in”. I would think he was gay but last time he came in he put his wife’s phone number in for rewards.
Is he trying to flirt a little? Why would he feel the need to bring that up? I told a couple people and they think he was flirting.
