Gate
Pieces that were fetched to a gate for somebody who did not come. This is what SavaFlow has recorded, not what is standing there, so go and look before recording anything.
What is recorded at each gate
Reading what is recorded at each gate.
Waiting to go back
Reading what is recorded at the gates.
Recording a return puts a piece back on a shelf and does nothing else. It does not cancel or complete anybody's visit, does not tell the customer anything, and is not held against them or against you. Nothing here has been run against a live database yet.
