Gaming as a cashier in grocery store

Any tips on the most optimal way to day game as a cashier in a grocery store?
Since I’m working, I try to show interest more subtly, by making strong eye contact and smiling, bringing good vibes, and complimenting maybe the girls style, but the numbers I’ve gotten so far have been flakey. Should I be more direct? Mention I think she’s cute
I was also thinking of maybe going for an IG close to build more comfort, since the interactions can be quick.

Some interactions are so quick, like the girls just buying an energy drink, I don’t have enough time to build comfort in those 30-50 second interactions. Some of these girls are exactly my type and I just have to shoot my shot. Here’s an example of a number I got last week that ghosted.

Me: “hey, How’s your Monday going?” (Making good eye contact and smiling)

Her: “ oh it’s okay. Nothing exciting :/“

Me: “Oh damn, that’s no fun. Ay you ever been to Andy’s?”

Her: “ No, but i hear it’s really good!”

Me: “Whaaat, it’s amazing! See now that’s exciting, we should go sometime”

Her: smiling and giggling “Yeah! I’m down”

She writes down her number on the receipt and I said cool I’ll talk to you later. It was super busy at this time and she was only buying couple things, so it wasn’t that long.

I’m cool with all my coworkers and I’m always in good spirits, regular customers tell me I’m their favorite cashier, etc. I’m f having a good time joking with all customers and it gets me in a good social rhythm, some girls even try to be part of the conversation after seeing a customer and me laughing and vibing.
