Shoemaker, one who behaves condescendingly (4)
I believe the answer is:
snob
I believe this is a double definition.
'shoemaker' is the first definition.
(term for a cobbler)
'one who behaves condescendingly' is the second definition.
(Other definitions for snob that I've seen before include "One who thinks others socially inferior" , "One who considers himself socially superior" , "blackleg" , "Toffee-nose" , "One despising inferiors" .)
