I managed a Dominoes while going back to school. One thing I can tell you is that the Drivers do the most work of anyone that work there. They answer phones, sometimes make pizzas, and box up pizzas. Most places pay the driver $.50-$1.00 per delivery(not trip), which is usually 10-15 orders per night depending on the night. This is payed by the company, and was payed before they started with delivery charges. Delivery charges were put in so that the company could make up the money in rising food costs without raising their prices. Its essentially so they can still charge $9.99 a pizza or what ever to stay in line with national advertising. Cheese costs are what drive pizza, the price fluctuates week to week and makes oil price rises and falls look petty.
