We sat about on road for attendant (7)
I believe the answer is:
steward
'for attendant' is the definition.
(steward is a kind of attendant)
'we sat about on road' is the wordplay.
'about' indicates anagramming the letters.
'on' says to put letters next to each other.
'road' becomes 'rd' (abbreviation).
'we'+'sat'='wesat'
'wesat' anagrammed gives 'stewa'.
'stewa'+'rd'='STEWARD'
(Other definitions for steward that I've seen before include "Crowd-control official" , "race course official" , "Ship/aircraft attendant" , "Attendant on ship - race official" , "bailiff" .)
