'urger left in a hurry feeling' is the wordplay.
'urger left' can be anagrammed to 'REGRETFUL'.
Though, I am not sure how this is indicated.

Can you help me to learn more?

(Other definitions for regretful that I've seen before include "Wishing something hadn't happened" , "Feeling guilt over something" , "penitent" , "but not Ms Piaf" , "Miss Otis was" .)
