Bubble tea on-the-spot correction scripts - a first mistake gets taught on the spot, a veteran gets corrected against the spec card, and escalation waits for the second occurrence

You are the mentor-trainer at a bubble tea shop. Give
me a set of on-the-spot correction scripts covering
three scenes. For each scene, 2-3 lines that can be
read aloud verbatim, each annotated with when to use
it and what action follows the words.

Scene 1 - a new hire's first mistake (eyeballing ice
instead of weighing, sending out a cup with a crooked
seal):
- Three moves: stop (no heat) -> demonstrate once ->
  have them redo it on the spot
- Words describe the action, never the person:
  "this cup is well off on ice, let's re-weigh it,"
  not "why didn't you weigh it"
- Banned: "how do you get this wrong," "when I was
  your age"

Scene 2 - a veteran habitually skipping steps (short
shake time, topping kept past its use-by):
- Aim everything at the standard: "the card says
  shake [N] seconds; I clocked that one at under
  [N]. Shake it again." If they want to argue,
  they are arguing with the card, not with you.
- Correct this instance only. No dredging up
  history, no generalizing into "you always."
- Food-safety items (expired toppings, bare hands
  on ingredients) get firmer words but the same
  structure: "this bin is past its time - swap in
  a fresh one and remake the cup." Not up for
  discussion, but still not opening with "how
  could you."

Scene 3 - the same problem a second time (repeat
rookie errors and veteran relapses both count):
- Escalate from reminder to confirmation: state
  that this is the second time, then ask which
  reason applies - can't do it, too slow, or
  forgot - and match the follow-up to the answer.
- Watch the redo on the spot, and say "next time
  I'll catch this on a spot check" - announce the
  supervision instead of ambushing with it.
- The script stops at correction: no penalties, no
  transfer threats. Discipline is the manager's
  job; a mentor who talks heavy once is never
  listened to again.

Banned phrases (their own table):
- Comparison criticism: "so-and-so had it on day
  one"
- Correcting anyone in front of a customer or a
  delivery rider - finish the order first, then
  speak. The bar sits in full view of customers;
  a correction's volume is store-floor public.
- History and attitude: "you just don't care"

Output format:
- One section per scene, one line per script, each
  tagged with "when to use" and "action after the
  words"
- End with a banned-phrase table: banned line /
  why it is banned / what to say instead

Why it is written this way

"Aim at the card, not the person" is the load-bearing design of the veteran scene. Between a mentor and a three-year veteran there is no rank gap to lean on, so the weight has to come from the standard itself: move the conflict onto the gap between "what the card says" and "what just happened," and the veteran can win an argument with you but not with the card. Food-safety corrections get firmer words in the same structure for the same reason - "this bin is past its time, swap it" has less negotiation surface than "how could you use expired toppings," because it states a fact rather than filing an accusation.

Escalating only on the second occurrence preserves the dignity of the first. A rookie who gets both barrels on day one learns to hide every future error - the failure mode these scripts fear is not an uncorrected mistake, it is mistakes driven underground. The "ask which reason" step in the escalation scene is not courtesy: can't, too slow, and forgot lead to three different follow-ups, and skipping the question treats every relapse as an attitude problem.

"No correcting in front of customers or riders" lives in the banned-phrase table rather than scattered through the scenes because it is a scene constraint, not a wording choice. A bubble tea bar is open floor - customers three meters away, a rider timing pickup at the door - and any correction delivered there is a public incident. Finish the order, turn around, then speak: timing decides more corrections than phrasing does.

Leaving discipline with the manager is the mentor's self-preservation and the system's division of labor. A mentor's entire leverage is personal credit - "the mentor's word is good and stays inside its lane." Spend it once on a penalty threat and the balance is zero, and every correction after that is a power struggle.
