Last opportunity, before starting lunch, to get a seat (5)
I believe the answer is:
stall
'a seat' is the definition.
(I've seen this before)
'last opportunity before starting lunch' is the wordplay.
I cannot really see how this works, but
an anagram of 'last' is 'stal' which is within the answer.
A single letter 'l' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to get' acts as a link.
Can you help me to learn more?
(Other definitions for stall that I've seen before include "Hold up" , "Seat - prevaricate" , "Hedge" , "Delay - booth for selling goods" , "Put off" .)
