Request to get computer support? That's to invite trouble (3,3,2)
I believe the answer is:
ask for it
'to invite trouble' is the definition.
(I've seen this before)
'request to get computer support?' is the wordplay.
I cannot really understand how this works, but
'request' could be 'askfor' (synonyms) and 'askfor' is present in the answer.
The remaining letters 'it' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'that's' is the link.
Can you help me to learn more?
(Other definitions for ask for it that I've seen before include "Informally, invite or deserve trouble" , "court problems?" , "Invite retaliation, provoke trouble" , "Invite ill" , "invite punishment" .)
