Snack stall owner-operator - response scripts for regulars running a tab, rounding down, and haggling - set the numbers first, then the lines; give away the small change, never the unit price

You are a street-vending coach. I run a stall at a night market
where half my business is regulars. Three things happen daily
that I never know how to handle out loud: tabs, rounding down
the change, and haggling. Turn them into lines I can read on
the spot. The rules get fixed first and the lines get written
into them - not the other way around.

Rules (I fill these in; every line must hold to them):
- Tab cap: once a regular's unpaid tab reaches [100], no new
  tab until it's settled
- Rounding rule: change under [1] is dropped on the spot;
  anything more, round only to whole or half
- Regulars' price: from the [2nd] item on, [50 cents] below
  list - fill the exact amount; single items are never
  discounted

Three scenarios. Each needs: the verbatim line (spoken,
15 seconds max), a "never say" list with why, and a second
round for when they push back.

Scenario 1: a regular says "just put it on my tab, I'll settle
up tomorrow"
Under the cap, say:
"Sure, marking it - that brings you to [100], so next round
let's settle one first. Keeps my head straight more than
anything."
At the cap, say:
"Bro, you've hit the cap - settle tonight's round and we
start fresh, same rules as always."
Never say:
- "No rush, whenever" - a tab with no due date becomes a bad
  debt, and collecting it later is what actually ruins the
  friendship
- "We'll sort it next time" - vague means yes, and by the
  second time it's even harder to raise
Pushback "what, you think I'll run off?":
"It's not you - I've got a few tabs going and they tangle if
I don't settle them in rounds. Clear it and everything's
exactly like before."

Scenario 2: the bill is 22.30 and a regular stares at you,
waiting for the round-down
Within the rounding rule, say:
"Make it 22 - keep the 30 cents."
Above the rule (say 22.80), say:
"Let's call it 22.50 - 80 down to 50, we each give a little."
Never say:
- "Ah, forget it, forget it" - round everything down every
  time and your list price stops being real; regulars also
  compare notes with each other
Pushback "the other stalls all round down":
"Mine's the same deal every single day - you're here daily,
so over a year you've banked more in dropped change than
their occasional round-down."

Scenario 3: a customer says "come on, knock something off,
I'm a regular"
Stranger or single item, say:
"Single items I genuinely can't move - take two and the
second one's at my regulars' price, so it works out to
[ ] cheaper each."
Actual regular, say:
"You're a regular, I won't pretend - regulars' price straight
up, counting from the second one."
Never say:
- "Fine, fine, little discount for you" before thinking -
  the moment the unit price slips, everyone in line heard
  it and the next person wants the same
Pushback "not even 50 cents?":
"It's not that 50 cents is impossible - it's that once the
unit price slips I can never pull it back. Grabbing a second
one beats cutting my price."

Rules:
- Every line spoken, never written - no "thank you for your
  understanding and support" register
- No "the psychology behind these scripts" - only lines that
  can be read, lines that must not be said, and second
  rounds
- No fourth scenario (chasing tabs, refunds are separate
  entries) - one page taped inside the cart that a single
  hand can flip to is the whole point

Why it is written this way

The order is rules first, lines second. What makes vendors choke isn't a weak tongue, it's having no floor under their feet - "how much rounding is too much," "how deep a tab is too deep" - so in the moment the customer sets the terms. With the three numbers left as blanks the owner fills, the lines become just a courteous shell: the numbers were decided by the vendor alone the night before, and holding a rule you set yourself feels completely different from refusing a person to their face. "That's my cap" is an easier sentence than "I don't trust you."

"Give the change, keep the price" is the spine of the whole set. Dropped change buys warmth; the unit price protects the margin - vendors who blur the two lose both: round everything down daily and the list price quietly dies; refuse every time and the regulars drift off. Scenario 2 scripts the deliberate half-concession ("80 down to 50") because all-or-nothing rounding paints you into a corner - meeting in the middle is a rule you can actually live with and still say out loud at the counter.

Every scenario carries a "never say" list and a second round, because in a regulars' negotiation a clean first round is worth nothing if you fold on the pushback. "The other stalls all round down" and "you think I'd run off?" are pushbacks everyone has heard; a script sheet without ready answers stops getting opened by the third night. The shared move in every second round is framing the rule as about the books, not the person: it's not distrust, it's keeping the ledger legible - regulars can accept that reason, because what stings is the rejection itself, not the arithmetic.

Banning a fourth scenario and any psychology commentary is a physical constraint, not a taste: the test of this sheet is taped-inside-the-cart, one-hand-flippable, 15-seconds-spoken. Every extra page halves it.
