The five notices the counter sends, and how often each one goes out

Each one is a separate choice with its own rhythm and its own audience. The assistant changes exactly the one you name and leaves the rest alone.

Code	What it is	What it covers	Plan	Turnaround
`TK-ARR`	Just arrived	What came in off the bench this week with its honest grade — haze, separation, a sticky slow speed said out loud rather than discovered at home.	Anyone following	Saturday mornings, weekly
`TK-WANT`	Your want list	A single message the day something on your own list turns up. Nothing else is ever sent on this one.	Counter card and above	Only when it happens, sometimes never
`TK-BENCH`	Bench ready	Your repair is finished, what was done to it, what it came to, and until when it is held at the counter.	Anyone with a repair in	The day the job closes
`TK-TRADE`	Trade-in offers	What the shop is short of and paying well for this month, with the grading the offer assumes.	Trade priority members	First of the month
`TK-DARK`	Darkroom nights	The monthly evening upstairs: who is printing, what is being demonstrated, and the six places that are not already gone.	Anyone following	Ten days ahead, monthly

The assistant reads this same table through its list_services tool, so what it tells you and what this page says cannot drift apart.
