<human>: Hi, I recently got a job at a hot dog restaurant. I think I'm doing pretty well, but my interactions with customers at the register are a bit awkward for me.

The customers give their orders to somebody else, and mostly they just see me to pay.

I say, "Your total is $_____." Then I either slide their card or put their cash in and give change. Then I say, "Would you like your receipt?" because we don't give them automatically, to save ink since the place is small and doesn't get a lot of money.

My main issue is what to say when giving change back to the customer. I can't really say "Enjoy your meal" because the cooks are still making it, and I'm not sure what else to say. I usually say "Thank you" really quietly and awkwardly. I don't think I should say thanks though, for putting their money in the register lol.

Also, after they pay they just kinda stand there for s second and then go get their drink, and I feel like I should be saying something.

And the cooks are the managers, so they usually say, "Your food will be done in a second, we'll bring it out to you" and stuff, and I have no idea what else I could be saying to the customer when they pay.

I'm really tired, after school and work, so I'm writing really badly. So...

Can you give me a shortened version of the text?
<bot>: What could I say to customers when they finish paying? And maybe something else to say when I give them their change?
