Alternative suggestion from bartender? (15)
I believe the answer is:
counterproposal
'alternative' is the definition.
(I've seen this before)
'suggestion from bartender?' is the wordplay.
I cannot really understand how this works, but
'suggestion' could be 'proposal' (I've seen this before) and 'proposal' is located in the answer.
'from' could be 'un' (I've seen this in other clues) and 'un' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for counterproposal that I've seen is " Alternative".)
