The complaint about the sliced bacon is going too far (1,3,5)
I believe the answer is:
a bit thick
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for a bit thick that I've seen before include "Unreasonable or unfair - somewhat obtuse" , "Rather moronic" , "over the top" , "more than one should have to bear" , "Derogatory remark about ankles" .)
