Crowd in rear of cafe accordingly getting coffee (8)
I believe the answer is:
espresso
'coffee' is the definition.
(espresso is a kind of coffee)
'crowd in rear of cafe accordingly' is the wordplay.
'crowd' becomes 'press' (press is a kind of crowd**).
'in' is an insertion indicator.
'rear of' indicates one should take the final letters.
'accordingly' becomes 'so' ('so' can be a synonym of 'accordingly').
The final letter of 'cafe' is 'e'.
'e'+'so'='eso'
'press' inserted into 'eso' is 'ESPRESSO'.
'getting' is the link.
(Other definitions for espresso that I've seen before include "Type of coffee" , "Kind of coffee made with steam" , "Coffee made under steam pressure" , "Italian-style coffee" , "Coffee drink" .)
