Fire engulfing new pub and food outlet
I believe the answer is:
snack bar
'food outlet' is the definition.
(I've seen this before)
'fire engulfing new pub' is the wordplay.
'fire' becomes 'sack' (dismiss someone from their job).
'engulfing' means one lot of letters goes inside another.
'new' becomes 'n'.
'pub' becomes 'bar' (I've seen this before).
'sack' enclosing 'n' is 'snack'.
'snack'+'bar'='SNACK-BAR'
'and' is the link.
(Other definitions for snack bar that I've seen before include "Light food outlet" , "Place serving light meals" , "Where light meals may be bought" , "Place to obtain light refreshments" , "Place to buy light meals" .)
