| there's no evidence that Person A knew, for certain, that Person C knew the middle name. Person A used intuition to obtain an answer, though it wasn't their own.
Provided the prize was offered in good faith and it was of trivial value, Person B should pay up. Consider the loss a LART for unclear specifications.
The easiest method to solve the argument that will likely ensue is to have Person C forfeit $10 -- $5 to each of A and B. A gets compensated for B's cheating. B gets their "prize," and C still makes omney for the information. |
