The water from the factory pipe water is never clean. As a proof, every time the boss tried to rear fish using the office pipe water, the fishes will die after a few changed of water. Ended up, the boss brought Diamond water for her fishes.
So, as much as possible, I will not drink the office water. I bring my own water from home. We did request her to place the o premium waters dispenser in the office but till today, no news about it.
We know that they try not to spend so much so we recommended the O Premium Waters because their rates are lower than others, they are offering free delivery and free use of a water cooler too. And still, they rather we die earlier than they spending more. :(
