Drink and get fired (4)
I believe the answer is:
shot
I believe this clue is a double definition.
'drink' is the first definition.
(I've seen this before)
'fired' is the second definition.
(shooting is a kind of firing)
'and get' is the link.
(Other definitions for shot that I've seen before include "Injection" , "Used a gun" , "Small drink of spirits" , "Ruined; photograph" , "glass of spirits" .)
