Does it seem like she’s into me?

So there’s a girl at my work (we’re both 18), and I never thought much about her until a few weeks ago. I was on register and I was gonna take my break and she covered me. She looked so pretty today, like-INSANELY pretty. She walks up and is like “have the best break ever while I cover this super busy line (it wasn’t busy at all”. And I said “thank you, it’s gonna be the best break I’ve ever had in my life”. I then pointed at the register and did a little swirl thing and said “it’s all yours now” and she said “wow thanks, really thanks, I’m gonna have so much fun” and I said “I figured you would”

When I get back from my break she says “you’re just back in time, the long line left”, I said “I bet it was busy for the whole time I was gone and as soon as I came back everyone just booked it out the door right? Everyone hurried and bagged their stuff and left” and she laughed and left and I said “thanks for covering my break btw”. And when I left she was on the other registers and she said “bye…be careful!” She sounded disappointed but idk if there was a reason for it. Does it seem like she’s into me?
