Bachelor, single friend, providing skeleton service? (4,5)
I believe the answer is:
bone china
'skeleton service?' is the definition.
'bachelor single friend' is the wordplay.
'bachelor' becomes 'b' (abbreviation e.g. BA=Bachelor of Arts).
'single' becomes 'one' (I've seen this before).
'friend' becomes 'china' (cockney rhyming slang, mate is china plate).
'b'+'one'+'china'='BONE CHINA'
'providing' acts as a link.
(Other definitions for bone china that I've seen before include "Fine things perhaps thrown" , "Material from Potter" , "Form of white porcelain" , "Type of fine porcelain" , "fragile" .)
