Retail customer ignoring the first jumper (6)
I believe the answer is:
hopper
'jumper' is the definition.
(I know that hopper is a type of jumper)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for hopper that I've seen before include "What brings grist to the mill?" , "One-legged" , "Cricket, perhaps" , "Container carrying seed for sowing" , "Kentish farm" .)
