Standing behind stuff inside motorway shop (7,7)
I believe the answer is:
filling station
'motorway shop' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'standing behind stuff' is the wordplay.
I cannot really see how this works, but
'stuff' could be 'filling' (filling is a kind of stuff) and 'filling' is present in the answer.
The remaining letters 'station' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'inside' is the link.
Can you help me to learn more?
(Other definitions for filling station that I've seen before include "where Americans get gas" , "where juice is sold" , "Place for dental work" , "Roadside" , "Place to get petrol" .)
