Q: Is it Beer Monday or Wine Tuesday that is unsatisfactory? (3,6,2,1,5)

'wine tuesday that is unsatisfactory?' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'q is it beer monday' is the wordplay.
I cannot really see how this works, but
'is' is present in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found in the answer.
'beer' could be 'ale' (I've seen this before) and 'ale' is found within the answer.
'monday' could be 'mon' (synonyms) and 'mon' is located in the answer.
This explanation may well be incorrect...

'or' is the link.

Can you help me to learn more?
