Can you help me to order Chinese food?
What do you want?
Can I get an order of sweet and sour chicken as well?
You need 2 orders of lo mein and 2 orders sweet and sour chicken, is that correct?
Oh, no, two orders of lo mein and one order of sweet and sour chicken. Do those come in different sizes lo mein?
No, just one size.
All right. Well, that should be good. I'm ordering for two people.
I have your personal details on file. Your order will be ready for pick-up in about 20 minutes.
