A Customer can be:

• REGISTERED_ONLINE
  Customer creates an user account and self-registers on Store website.
• GUEST
  Customer makes a phone call to the Store to place an Order and a Store Employee registers the mandatory information about Customer: First Name, Last name, Phone, etc.
• ANONYMOUS
  Customer places an Order in Store (or at a Drive-In station) and the Order is picked-up by Customer as soon as the Order is paid. In this case there is no information recorded about Customer.
  If an ANONYMOUS Customer asks for a detailed invoice, then the Store Employee wil register the mandatory information about Customer and in this case Customer becomes a GUEST Customer.
