Tipsy loner in bar draining litre? It requires little thought (2-7)
I believe the answer is:
no-brainer
'it requires little thought' is the definition.
(I've seen this before)
'tipsy loner in bar draining litre?' is the wordplay.
I cannot quite see how this works, but
'in' is found in the answer.
an anagram of 'bar' is 'bra' which is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for no-brainer that I've seen before include "Something requiring no mental thought" , "Trivial problem" , "Obvious choice" , "Something needing little mental effort" , "An easy decision" .)
