2. Milkman

The job of milkman is still in practice today. However, there are very few milkman still left. Due to refrigeration and mass production, everybody has milk in their homes at all times. You go to supermarket and buy preserved milk. Half a century ago, you didn’t have any milk until the milkman arrived and delivered it.

Milk production and delivery was a very lucrative business. Companies employed hundreds, in some cases thousands of milkmen. There were special vehicles designed for milk delivery called “milk float”. The need for daily delivery arose from the fact that milk would go bad if you stored it. Every house ordered the quantity they needed for one day and get a fresh supply next day.
