It’s Friday night and you do not feel like cooking dinner so you decide to order 2 large pizzas. The pre-tax total is $25.98; the delivery person delivers your pizza in a timely manner. How much of a tip should you give the delivery person for the service?
Hint: 10% of the bill (excluding tax), at least $1 for bills up to $10. You should tip 15%-20% for a difficult delivery.
