Pizza girl delivers extra topping

Kelsie has been working as a delivery girl for as long as she can remember. Some days are better than others, people usually tip her about 10%. She has to be on the run all day to make a decent living. Sometimes she wishes to receive more than a tip. This is her lucky day as the pizza she's about to deliver will end up with some extra topping. That's how a pizza should be, filled with meat and extra topping!
