(I am a female working drive-thru with a male coworker. We are both able to speak to the customer.)

Me: “Hi, welcome to [shop name]. What can I get for you?”

Customer: “I’d like a [coffee drink] and [sandwich], thanks.”

(At this point, I am busy starting work on the sandwich, so my hands aren’t free to hit the button to respond to the customer.)

Male coworker: “Alright, that will be [price] at the window, please.”

Customer: “What? You sure went through puberty in a hurry!”
