first class

In line at a pizza joint, a man and his son decide to get three pizzas. At the cashier, they changed their mind and asked to get the newly baked pizza that came out of the oven. The cashier then decided that since the pizza was already out for an hour, to throw it away because of the bacteria in the air. The blonde behind the man and son didn't know, so she said "why are you throwing those away? There are kids in Africa who are starving." The cashier then said "If I sent these to Africa, they'd have mold on them." The blonde replied "That's why you send it first class, duh!"
