Slight baker's products rejected (4)
I believe the answer is:
snub
'slight' is the definition.
(both can mean to treat someone disrespectfully)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for snub that I've seen before include "Blank" , "Slight - short and blunt - humiliation" , "Deliberate insult" , "Rude rejection" , "Cut; ignore" .)
