It has been a couple of years since we've ordered pizza (it is expensive). But I thought you may be interested in seeing how they are delivered...well, sort of, I only have photos of the vehicles.
The pizza guys zoom around on these three wheeled mopeds, most have these heated cubicles on the back for the pizza.
At Christmas time, they dress in santa suits (I really want a photo of this!!)
Some of the more recent models have a roof and winshield. I also noticed that the Domino mopeds have a warming cubicle on the front of their mopeds too, which are apparently used to hold their helmets when they are not on delivery.
Are there interesting delivery vehicles where you live?
