I managed finally, after lots of prodding of the site manager, to get a water cooler installed down here in our department. The water supply down here tastes funny (and is usually warm) so I complained. Unfortunately they’ve plumbed it into the same water source as the tap (duh, I did warn them of this) but with it being cooled, I can no longer taste the fun.
Increased efficiency due to being properly watered: 10%.
Loss of efficiency due to many more trips to the toilet: 2%. Bonus!
I wonder if I can get them to install a urinal down here now. Obviously not in the kitchen, that wouldn’t be hygenic, but there is space in the server room.
