[Year 12 SofDev] Oliver's Mexican Cantina

[Mark KELLY]

Hi Alan. The kitchen display, to my way of thinking, is not connected to the
Cantina software at all (a conscious decision by the author to limit the
scope of the mobile device's functional requirements.)

Between the mobile software and the kitchen system (which is an external
entity) lies the transmitting software (also an external entity), and you
don't show communications between external entities.

2 pigs and 1 yam's worth (for our Papua New Guinean readers)

Regards
Mark
