Girl's Behavior

Guys, Is she interested in me?

So there's this customer I seened a couple months ago I told her I liked her Hoodie and that's it she thanks me. Months later she shows up to my job again I noticed her asked her what will she like to order, non chalantly, she tells me her order, after that she goes I seened you before "my name is Lisa what's your name" I then tell her, then reach out my arms to shake her hand and say "It's nice to be acquainted" we then talk for a little while I ring her up then she leaves the cash register. So after a couple of hours goes by she passes by register she then leaves and waves Bye at me while smiling. So yesterday she came into the store she then says "HI" while waving at me happy. So I take her order first thing she says "I'm soo high I need a tea", I recommended a tea I then give it to her, she then say thank you while staring at me. So hours passes by she's sitting in the back with her friend their about to leave, and before she left she goes have a "good night", then says have a "nice night" while giggle and staring at me I do the same.
Guys, Is she interested in me?
