I am particularly hooked on this idea.Distributing free low concentrated sugar free tea :-) I remember a case study i read some years ago about the difference in drinking culture between india and china.The Chinese factory workers often have a 24 hour boiling pot of low concentrated green tea parked where they constantly consume small portions of during their day.AFI remember around 70% of water intake for them was via this medium. That could be an out of the box solution.:-)
