Blushing and hiding amusement when annoyed customer gets what they deserve? (6)
I believe the answer is:
refund
'blushing and hiding' is the definition.
I can't tell whether this defines the answer.
'amusement when annoyed customer gets what they deserve?' is the wordplay.
I cannot quite see how this works, but
'amusement' could be 'fun' (I've seen this in another clue) and 'fun' is found in the answer.
The remaining letters 'red' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for refund that I've seen before include "Cash back" , "money to be paid back" , "Give back" , "Money returned" .)
