pizza delivery

A pizza chain is facing some tough deliveries in Japan with a difficult winter on it's way.  So they have decided to test deliveries by reindeer.  The animals would have a hot box strapped to their back and would make the journey alone.  A lot of details have to be dealt with before it happens but the pizza chain is hopeful.  I can see a lot of problems with this plan...the reindeer runs off...the box falls off it's back...someone steals the box en route...other animals smell the food and try to get it...the reindeer gets lost...the list goes on.  I think I'd prefer the delivery driver.  reindeer
