A few lines on how to behave in pub (7)
I believe the answer is:
barcode
'a few' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'lines on how to behave in pub' is the wordplay.
I cannot quite understand how this works, but
'lines' could be 'ode' (I've seen this before) and 'ode' is found within the answer.
'pub' could be 'bar' (both are drinking establishments) and 'bar' is found in the answer.
A single letter 'c' remains 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?
(Another definition for barcode that I've seen is " may be scanned".)
