Carrier hurried in back street to get drink (11)
I believe the answer is:
transporter
'carrier' is the definition.
(I've seen this before)
'back street to get drink' is the wordplay.
'back street' becomes 'trans' (I can't explain this - if you can you should give a lot more credence to this answer).
'to get' is a charade indicator (letters next to each other).
'drink' becomes 'porter' (porter is a kind of drink).
'trans'+'porter'='TRANSPORTER'
'hurried in' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for transporter that I've seen before include "See 10" , "one giving rise to strong emotion?" , "Freight vehicle" , "HGV" , "Lorry" .)
