Buyer of a lot of neat alcohol right after a drink (9)
I believe the answer is:
purchaser
'buyer' is the definition.
(synonyms)
'lot of neat alcohol right after a drink' is the wordplay.
'lot of neat alcohol right' becomes 'pur' (I can't explain this - if you can you should believe this answer much more).
'after' means one lot of letters go next to another.
'a drink' becomes 'chaser' (as in a shot and chaser).
'pur'+'chaser'='PURCHASER'
'of a' is the link.
Can you help me to learn more?
(Other definitions for purchaser that I've seen before include "Buyer" , "I'll buy" , "Punter" , "customer" , "Shopper" .)
