Re: The Diner Check Problem

I like Lomax's last succinct answer.
Dave_C's question "how the hell did each person pay a fraction of a penny?", possibly warrants an explanation.
The question of fractions of a shilling never became an issue, because the diners took a whole shilling each back and gave 2 whole shillings to the waiter.
IF the diners had decided not to tip the waiter, THEN, and only THEN, fractions of a shilling would have become an issue. They would have each been entitled to one third of 5 shillings refund, which would have been 1.6667 shillings, and in that case only, they would have paid 8.3333 shillings each. (This, by the way is the mathematical share of what they each paid to the restaurant). Tipping 0.6667 shillings each to the waiter kept all of the transactions in whole dollars, so that fractions never became an issue.
