Staff allowed to get something to eat (7)
I believe the answer is:
pikelet
'something to eat' is the definition.
(type of crumpet)
'staff allowed' is the wordplay.
'staff' becomes 'pike' (both can mean a pole or stick).
'allowed' becomes 'let' (to let is to allow or permit).
'pike'+'let'='PIKELET'
'to get' is the link.
(Other definitions for pikelet that I've seen before include "Type of crumpet" , "15 [TEACAKE]" , "afternoon treat, perhaps" , "local crumpet" , "Thin kind of crumpet" .)
