Get your minds out of the gutter!! Its not what you think!
I still have a milkman to deliver my milk and eggs. Friends say it is cheaper to buy milk in the supermarket - but I know it isn't. The last time I popped into Asda for just milk, I spent £80 - and I did really only need milk! I leave him my empties, and they get reused lots more times and so I don't have those horrible big plastic containers to dispose of, and he never misses a day - even when it is really bad snow. He delivers it at 4am, so its always fresh for my cornflakes. He also delivers my eggs. I know that he picks these himself from a local farmer, and I often end up with a box full of double yolkers. He takes the boxes back when they are empty - so no land fill there either. When I see how much plastic my pals recycle - just from milk and eggs - I am astounded.
My son also pointed out that we are keeping him in a job too, and for that reason alone, I think its worth keeping the milkman.
