My workplace had a contaminated supply (petrochemicals) and we were given a "Do Not Drink" notice, so the management got a load of two litre bottles in.
We were getting through two bottles a day just making tea (and other hot drinks).
Heres the thing, there are only three employees and one of them works a half day
So the standard 'two litres per person per day' would barely cover us for a working day , let alone cooking and drinking at home.
This leads me to believe that either
A) The supposed minimum requirement is wrong
Or
B) We have far too many tea breaks/ Our mugs are too big.
Has anyone done a test under real world conditions ?
