Crossword Genius

With no waiting in line, chain store's popular (4,1,4)

Ross

I believe the answer is:

like a shot

'with no waiting' is the definition.
(like a shot means immediately)

'line chain store's popular' is the wordplay.
'line' becomes 'l' (used when specifying particular lines from a poem).
'chain store's' becomes 'IKEA's' (IKEA is a chain of furniture shops).
'popular' becomes 'hot' (hot can mean popular or trendy).
'l'+'ikeas'+'hot'='LIKE A SHOT'

'in' acts as a link.

(Other definitions for like a shot that I've seen before include "Enjoy a nip" , "to demonstrate without hesitation" , "Lout" , "straightaway?" , "looking round, in field event?" .)

I've seen this clue in The Times.
