In a vore world, preys needs to be prepared to deliver a pizza to a pred. They usually make delivery a part of their meals.
For this reason, pizzerias try to put in their differentials the possibility of seasoning the delivery person to be eaten when he arrives. It seems harmful and not lucrative, because not all preds have the habit of making their bellies go into endo mode and end up being digested making less people to work in this job, but if the pred is nice and likes endos, the delivery man can earn fat wages, and that's why Dynny is in this job.
