..... In a supermarket, pick up carton, pay for it and leave, simple.
.... another local business goes to the wall because the money has gone from the local economy to Tesco/Asda/etc .... Simple! 
I agree with the sentiment, however the milk delivery companies were not really local businesses, they were big National concerns. And if their employees had been honest I would still be using them.
Are you sure you wernt a victim of milk theft.....goes on quite a bit, milk getting pinched from doorsteps
esp if you dont have a front garden/path to your frontdoor.
This wasn't a case of milk getting nicked from the door, it was about being charged when we were away and had cancelled, disputes about the quantities, even disputes about whether we had paid or not (started to write cheques so there was proof), all sorts of things. No, life is complicated enough, the supermarket it simpler.
