Text-based Storyboard — Checkout Zero

Kit 11 · Checkout Zero · deliverable · designed and built by I Wayan Usada · fictional supermarket

Design premise

Four customers on a first-week shift. Revised after the build so it matches the 2D register and the 3D lane; both read checkout-data.js. The earlier storyboard described a different build and claimed twin dignity/speed scoring that was not implemented (the build had one /8 score).

Two axes, scored separately

Dignity (0–2 per reply): did the customer keep face?
Extra queue time (illustrative seconds per reply): what the reply costs the line. Budget 240 s over the shift.

Customer	Best reply	Dignity / seconds	Fastest reply	Dignity / seconds
Older gentleman counting coins	"Take your time" + one sentence to the queue	2 / +20	scan louder, rush him	0 / −5
Student, deposit bottles, no receipt	send her to the machine, hold her basket	2 / +40	"regels zijn regels"	1 / 0
Parent, child, balloons, cake	child holds balloons, cold chain first	2 / +15	instruct the parent, crush the cake	0 / +10
Declined pin, queue of five, someone filming	quiet options, "even geduld" sign	2 / +60	call the supervisor across the floor	1 / +120

Returning the deposit without a receipt is a policy breach and fails the shift.

Pass rule

Dignity 6/8 or more, extra queue time ≤ 240 s, no breach. The fastest set of replies (65 s) fails on dignity (3/8); the best set takes 135 s and passes.

3D lane

Lane 2 at 17:30. The queue grows while the learner reads and decides (one more shopper every 9 s, up to three). That pressure is deliberate and not scored. After each reply the customer's posture shows the dignity outcome and the queue settles or gets restless.
