W-Am: Yes, but I forgot to bring it today.
M-Cn: Unfortunately, I can't look up your phone number because our computer system isn't working, so I can't give you a discount today.
W-Am: OK. I understand. Oh, and I took this bottle of soy sauce from the shelf, but I don't want to buy it now.
M-Cn: That's fine, I know where it belongs. Now, will you be paying with cash or credit?
