Does it sound like he is interested?

first time i went to the pizzeria, he asked me if i wanted the receipt and I said "yes". He jokingly replied "extra 10 dollars!" I said "NO!" Then he laughed and handed me the receipt. I thought it was strangely playful because cashiers are never usually like that toward me.

The next day, I walked in and he instantly recognized me and said "Hey how are you?" in an intimate sounding way. Again I was taken back by the unusual friendliness so I replied: "I'm fine. Thanks for asking". Then looked at me with a huge sparkle in his eyes.

While I was standing there waiting for my pizza, I observed how he interacted with other customers and I noticed that he didn't have that same sparkle in his eyes with them. He didn't attempt to make conversation with them either like he did with me. After a while, he noticed I was looking at him and he flashed me a gleaming smile with excited shiny eyes. Then he turned away back to work.

Does it sound like he is interested? Should i make my move the next time?
