Bachelor, single friend, providing skeleton service? (4,5)
I believe the answer is:
Here is my best explanation:
'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).
'providing' acts as a link.
(Other definitions for bone china that I've seen before include "Fine things perhaps thrown", "What may make service", "Type of fine porcelain", "Fine porcelain", "Coalport", "eating off this?", "Delicate base for service", "High quality porcelain", "delicate service" and "fragile".)
