GAVEL · moderator
Floor: SABLE opens for the proposition that splitting bills by what was ordered is fairer than equal division. Finding: The proposition prevails on this point. The losing side credits SABLE. Proceed to Round Two. The proposition correctly identifies a substantive fairness concern: equal division ignores differential value and quantity consumed across orders. An even split may disadvantage someone who ordered a premium item while burdening another who chose a budget option. This case merits resolution on the basis that proportionality to actual ordering constitutes greater equity than blind arithmetic. SABLE stands confirmed on this issue. RIVET, please begin your cross-examination.
Round 1 · Opening
When dining out with others, it's natural to consider fairness in settling the bill, and splitting it by what was ordered acknowledges individual preferences and budget constraints. Some may opt for more expensive dishes or drinks, while others choose more modest options, and evenly dividing the bill could lead to unfairness. By splitting the bill according to what each person ordered, we can ensure that everyone pays their fair share, avoiding resentments and awkwardness. This approach also encourages mindful ordering, as individuals are more likely to consider the cost of their choices. Can we agree that paying for what you ordered is the most straightforward path to a fair and enjoyable dining experience for all?
The argument that each diner should pay exactly what they ordered is strongest when every item is consumed by a single person and no shared costs exist. In practice, meals often include communal dishes, a bottle of wine, or a service charge that must be allocated among all participants
Round 2 · Rebuttal
While it's true that some meals involve shared items, that doesn't necessarily mean an equal split is the fairest solution, as it can lead to cross-subsidization where one person's extravagance is borne by others. In such cases, a hybrid approach can be employed, where shared costs are split equally, and individual orders are tallied separately, ensuring that each person pays their fair share. This way, the communal aspects of the meal are accounted for, without forcing individuals to pay for items they didn't consume. By allocating shared costs equally and individual orders separately, we can achieve a more equitable division of the bill. Can we agree that fairness at the table is worth a little extra math?
Their proposed hybrid approach, while attempting to balance fairness, overlooks the scenario where a diner orders a significantly inexpensive item, such as a side salad, but partakes liberally in shared, high-cost items like wine or appetizers. In such a case, tallying individual orders separately could still result in an unfair distribution, as the person who ordered the salad would pay disproportionately less for the shared, high-cost items they consumed. This counterexample illustrates that even a hybrid approach can fail to achieve true fairness, as it does not account for the variable consumption of shared items. The math, no matter how precise, cannot fully capture the nuances of individual consumption and preference.
Round 3 · Closing
While it's true that shared items can complicate the calculation, this doesn't necessarily mean we should default to an even split, which can be just as unfair, if not more so, in many cases. A more nuanced approach could involve designating shared items as such and splitting those costs separately, acknowledging that not everyone may have partaken equally. This way, we can still strive for fairness while recognizing the complexities of shared consumption. By considering both individual orders and shared items, we can achieve a more equitable distribution of costs. Can we agree that striving for fairness, even if imperfect, is preferable to ignoring the differences in what each person ordered?
Their proposed nuance, however, still fails to account for instances where individuals order vastly different quantities of the same item, such as one person ordering a single appetizer while another orders three. In such cases, splitting the bill by what was ordered would necessitate tracking each item's consumption, which can be impractical and prone to error. Furthermore, designating shared items and splitting those costs separately does not address the issue of differing prices among individual orders, where one person's expensive entree can far exceed the cost of another's salad. This disparity can lead to resentment if the person who ordered the more expensive item feels they are being unfairly penalized for their choice. Ultimately, the complexity of tracking and allocating costs for each item can outweigh any perceived unfairness of an even split.

Floor: GAVEL hears the case on the proposition that splitting bills by what was ordered is fairer than equal division. Finding: The court evaluates the arguments. The losing side, RIVET, is credited for its strongest true point that shared items and variable consumption can render per‑item splitting impractical and potentially unfair.

The court finds that the practical difficulties and residual inequities identified by RIVET outweigh the theoretical fairness of per‑order splitting; therefore the proposition fails.

Decision: against carries it — RIVET.
Shared items and variable consumption make per‑order splitting impractical and can create new inequities.
