Charge that makes you feel robbed of pounds (3)
I believe the answer is:
fee
'charge' is the definition.
(fee is a kind of charge)
'feel robbed of pounds' is the wordplay.
'robbed of' suggests deleting specific letters.
'pounds' becomes 'l' (L can represent the monetary pound).
'feel' with 'l' taken away is 'FEE'.
'that makes you' acts as a link.
(Other definitions for fee that I've seen before include "Money paid for professional services" , "Amount paid for job" , "Sum payable to professional person for services" , "price" , "Sum payable to, say, barrister" .)
