Im/Politeness Implicatures [PDF ebook] 

This volume brings together two highly researched but also highly controversial concepts, those of politeness and implicature. A theory of implicature as social action and im/politeness as social practice is developed that opens up new ways of examining the relationship between them. It constitutes a fresh look at the issues involved that redresses the current imbalance between social and pragmatic accounts of im/politeness.
