This guy's actions are just not particularly defensible. He ordered not just oysters, but the whole meal by the sounds of it, with people he had just met and whose financial situation he was (presumably) unaware of. Expecting a split check is not reasonable. Either he came from such wealth that he didn't realize people ever consider the cost of an evening out--not a particularly satisfying rationale--or he was just clueless.
