Local employee bound to stop trade (9)
I believe the answer is:
bartender
'local employee' is the definition.
(I've seen this before)
'bound to stop trade' is the wordplay.
'bound to' becomes 'end' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'stop' indicates putting letters inside (stopping can mean blocking a gap).
'trade' becomes 'barter' (synonyms).
'end' put inside 'barter' is 'BARTENDER'.
Can you help me to learn more?
(Other definitions for bartender that I've seen before include "Someone serving drinks" , "One handling counter measures" , "He serves" , "Server in pub" , "The person doing the drinks" .)
