The Goat and Spirit Level
A pub in Ankh-Morpork where Moist von Lipwig left one of his boxes for those occasions when he may have needed to change his appearance very quickly.
Annotations
Likely a reference to the British pub "The Goat and Compasses". (Itself an allusion to concepts and ideas within Freemasonry: suggesting the said secret society would be more than usually welcome in there, the landlord being a member and covertly advertising this in the name and the picture on the pub sign. The upstairs meeting room might double as a Masonic lodge. In Ankh-Morpork, quite possibly connected to one of those secret societies common among gentlemen of common interests, of which Moist von Lipwig joined "quite a few". It is possible the landlord considers looking after the property of a Lodge Brother and keeping it secret from the profane eyes of the Watch is a sacred duty.)
