What's wrong with serving coffee anyway? (assuming the post was used as a taunt). I love my coffee & am always grateful for a free cup!! It's fun to see if you can make a decent cup with the galley brewer (debatable!!).
Controlled rest is like a spare tyre....if you have a flat on a drive, you're going to use it....but you shouldn't be driving around with it on all the time. It should be kept in reserve whilst you look after the normal tyres.
