Discuss professional matters with last postal worker at the end of the week (4,4)
I believe the answer is:
talk shop
'discuss' is the definition.
(I know that talk shop is a more specific form of the action discuss)
'professional matters with last postal worker at the end of the week' is the wordplay.
I cannot quite see how this works, but
'matters' could be 'ks' (K is an example) and 'ks' is found within the answer.
'last' could be 't' (I've seen this in other clues) and 't' is present in the answer.
'of' could be 'o' and 'o' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for talk shop that I've seen before include "Speak about one's work" , "Discuss work at a social event" , "Discuss business out of hours" , "dwell on work" , "like company bosses may do" .)
