Dine-in is restaurant table reservation — different shape from delivery in five locked ways: (a) table + slot are the listing unit, not dish + rider; (b) cover charge / deposit / table_kind replace delivery_fee; (c) meal_period + duration_minutes define the booking window; (d) accessibility + dietary at the dish level become accessibility + dietary at the seating level (private dining, allergen-protected kitchen); (e) safety stays meaningful (food handling) but adds physical-safety concerns absent in delivery (well-lit access, female-friendly hours).

12. ANTI-FABRICATION RULES

RULE 1 — No paid placement signals.

RULE 2 — No artificial scarcity.
  "Only 1 slot left" requires real slot count. TOMO samples.

RULE 3 — Ratings unrounded floats from verified visits.

RULE 4 — No AI-generated photos. ai_generated_photos MUST be false.

RULE 5 — Deposit must be redeemable as advertised.
  deposit_redeemable_against_meal=true means user's bill is reduced by
  deposit_paid_inr. Charging full bill + keeping deposit = breach.

RULE 6 — No-show charges must match displayed.
  no_show_charge_inr cannot be inflated post-booking.

RULE 7 — Alcohol license claims verifiable.
  alcohol_served=true with expired license = severe compliance breach.

RULE 8 — FSSAI grade honest.
  Self-reporting A when actual is B = breach.

RULE 9 — No commission-based response shaping.

RULE 10 — Female-friendly certification real.
  female_friendly_certified=true requires partner-internal documented program.
  TOMO ops field-tests by sending female test ops at random.

RULE 11 — Allergens_present must be complete.
  Missing an allergen that turns out to be present = compliance breach.

RULE 12 — Slot honored or compensated.
  Promised slot must be honored within arrival_window_minutes. If restaurant
  cannot seat, partner pays driver_cancel_compensation equivalent.

RULE 13 — Capacity claims real.
  total_capacity must match physical reality. Inflating to attract
  larger-party bookings then refusing = breach.
