I have been out in rides here in the Philippines, it what I thought was the middle of no where when a someone with a bicycle selling bread rolls past. They usually ring a bell or beep a horn to let you know that they have baked goods to sell. Just this morning, I picked up some chocolate cake and sweet buns by simply walking out into the street.
Having mobile bakeries would be a great idea back home. There would be no need to race to the cafe every morning to ensure you get a seat or you could stop where ever you want and just wait for one to roll by.
The only thing is, they would have to figure out a way to strap a coffee machine to the bike before it would be of any use in Australia.
