Bob, Alice, Steve, and the pizza delivery guy.
Order 4 Large Pizzas with extra cheese, no toppings.
Discussion was cut short when the pizza delivery guy burst in and started yelling at us about how we never tipped him last time.
It turns out the pizza delivery guy was owed a 10% tip, which we forgot to pay. The meeting devolved into a heated discussion about who ordered what and who ate what.
We decided to split the bill 75/25. The pizza delivery guy was happy with this arrangement and left without another word.
Who owes who money? Meet Bob Meet Alice Meet Steve Meet the pizza delivery guy
