I was sent to JHQ G3 Ops to assist in GRANBY work. keen to make the right impression I attempted to have an early night in B Mess. Got lost in my new surroundings and found the bar. Had one Dortmunder, then another and after a fair few, went to the allotted bunk.
The next day was sheer hell, both for me ( trying to keep quiet) and for those in my office (when the quiet ones escaped).
Moral of the story - only drink Dortmunder when on desert island.
