Like this parking concession (3)
I believe the answer is:
sop
'concession' is the definition.
(sop is a kind of concession)
'like this parking' is the wordplay.
'like this' becomes 'so'.
'parking' becomes 'p'.
'so'+'p'='SOP'
(Other definitions for sop that I've seen before include "Propitiatory gift" , "A concession or bribe, once offered to Cerberus" , "Propitiatory offering" , "Piece of bread dipped in liquid, or a concession" , "Appeasing gift" .)
