Questions: Girl's Behavior

So, there’s this waitress that comes in everyday when I’m on watch.

Now, I haven’t really been saying “hi” to her specifically until recently and that’s when I go into eat during dinner.

Once I started doing this more directly towards her, she’s been doing the same to me whenever she sees me.

Even today, once I checked her into base, she was like “have a good day sir” specifically to me on her way out.

Then again, right after watch, I see her while I’m getting some grab N go breakfast, where she says hi again to me only while I’m with my crew.

Then finally, once I head out to my car, I see outside and she greets me again as I’m walking off.

She greets me quite a bit now, whenever she sees me.

We’ll it’s almost summer weather and I do love a pretty girl that has nice, clean and maintained girly feet. I usually take glances if given the opportunity.
Wondering how aware girls are about this and how they feel about it
