Cori is the owner and manager of a catering company known as "Cori's Catering Services" (CCS). CCS provides complete meals (breakfast, lunch, and dinner), as well as an assortment of hot and cold appetizers and drinks, for groups of 12 to 500.

CCS receives order in three main ways: e-mail, telephone, and personal office consultation. In some cases, the customer has an idea of what he/she wants; in others, the customer relies on Cori's expertise to select appropriate items.

For each catering job, Cori prepares an estimate for the client. She files one copy of the estimate and sends the other to client for approval. The client may make changes to estimate over the phone, via e-mail, or through a personal consultation. Once the estimate has been finalized, Cori prepares a catering contract for the client's signature. She requires a 50 percent deposit with the signed contract; the remaining catering fees can be paid within 30 days of the catering event.

Cori accepts cash and checks; she does not accept credit cards. The client signs the contract and sends it back to Cori. Cori also signs it, files a copy for her own records, and sends a copy with both signatures back to the client. Cori and her staff deliver the catering order as scheduled, and she bills the client for any remaining fees. The client pays the invoice within 30 days and Cori deposits the funds in her bank account.
