Where you might be kept waiting for a bit of bread? (8)
I believe the answer is:
doorstep
This clue is a double definition.
'where you might be kept waiting' is the first definition.
(you might be kept waiting at a doorstep)
'a bit of bread?' is the second definition.
(informal term for a large slice of bread)
'for' is the link.
(Other definitions for doorstep that I've seen before include "To conduct house-to-house interviews" , "Canvass locally" , "substantial amount of bread" , "Old song: ` `Oh Mother Kelly's ........' '" , "sliced bread" .)
