[Year 12 SofDev] DFD question

[Mark]

I had the same issue with the DFD and UCD for one of the programming
outcomes.
The restaurant customer would be an obvious actor/external entity in a
system that takes meal orders.
However since the waiter is the one interacting with the system, and the
customer is interacting with the waiter, the customer does not appear at
all in the system representation.

Sometimes what seems logical is not as it first appears.
