Eat quickly and run off (4)
I believe the answer is:
bolt
This clue is a double definition.
'eat quickly' is the first definition.
(I've seen this before)
'run off' is the second definition.
(synonyms)
'and' acts as a link.
(Other definitions for bolt that I've seen before include "From the blue, it's a big surprise" , "Find a bar" , "From the blue, it's a great surprise" , "Eat (one's food) quickly" , "Run away; fasten (door)" .)
