My last job I worked in an organisation where the boss used to insist that anyone getting a cup of tea then had to refill the kettle and reboil it immediately. Apparently this reduced the time the next person would be away from their desks waiting for the kettle to boil. If the water was in any way cool (maybe because no-one had gone to the kitchen for a bit.... ) he would send snotty e-mails to everyone reminding them.
Way too much time on his hands for a CEO of a large corporation, but never mind.
(Too much time, or too much of a control freak... hmmmm...... )
