Individual pinching something from the pot? (3,4)
I believe the answer is:
tea leaf
I believe this is a double definition.
'individual pinching' is the first definition.
(rhyming slang for thief - one who pinches things)
'something from the pot?' is the second definition.
(something from a teapot)
(Other definitions for tea leaf that I've seen before include "Cockney crook" , "Dried part of a plant, used to make cuppas" , "source of drink?" , "might be spotted in China" , "One from Assam perhaps" .)
