I want to know the answer to the following question:
Retirees from what two professions often sought licenses for pubs?
All the background I'm provided with is that "Once obtained, licences were jealously protected by the licensees (who were expected to be generally present, not an absentee owner or company), and even "Occasional Licences" to serve drinks at temporary premises such as fêtes would usually be granted only to existing licensees.". Is that enough to answer the question?
