Bishop leaving rubbish in petrol station (6)
I believe the answer is:
garage
'petrol station' is the definition.
(as in a petrol garage)
'bishop leaving rubbish' is the wordplay.
'bishop' becomes 'B' (abbreviation used in chess).
'leaving' is a deletion indicator.
'rubbish' becomes 'garbage' (I've seen this before).
'garbage' with 'b' taken away is 'GARAGE'.
'in' is the link.
(Other definitions for garage that I've seen before include "Attachment to the house" , "Building for vehicles" , "workshop" , "Building for a car, or for its maintenance" , "Source of 4 dn or 16 dn" .)
