i reckon a great business initially would be for someone to have quality mineral dispensers as super markets, with decent renewable flagons ( say 5 or 10 litres, and a simple gizmo to pour it back home. Like a water bank. I could imagine it wouldn’t take long before all the major water suppliers cottoned on and did their own version. A top up card on account and just pass by and fill up at the end of your supermarket shop.
Does anyone have the go get to do something like this. I have thought for years it would be a great business.
