Need to order takeout burritos for three people, please.
Okay, what kind of burritos?
First, bean and cheese. Number two, carne asada. Number, three chicken. That's one of each of those.
One bean and cheese, one carne asada and one chicken burrito. Got it. Anything else?
Yes, I'd like three sides: sour cream, black beans, yellow rice.
One side of sour cream, one black beans and last yellow rice added.
That's right. Thank you. That'll work.
Anything else?
No, thank you.
Okay,  I have your personal details on file. Your order will be ready for pick-up in about 20 minutes. Enjoy.
