Four people are in a bar.

Ben owes Glen a drink. Glen owes Rhen two drinks. Rhen owes Sven three drinks. Sven owes Ben four drinks.

To settle up, what is the minimum number of drinks that need to be bought by who for whom?

Since the question regards that number BOUGHT by each man, then each man actually spends his own money on one drink, with the exception of Ben, who was apparently in VERY good spirits last time HE was at the bar, probably since it must have been payday. Therefore, Ben's the only one having happy hour today.
