Be in the red after milk supplier left drier in the kitchen (3,5)
I believe the answer is:
tea towel
'drier in the kitchen' is the definition.
'tea towel' can be an answer for 'drier' (I've seen this before). I'm unsure of the 'in the kitchen' bit.
'be in the red after milk supplier left' is the wordplay.
'be in the red' becomes 'owe' (I've seen this before).
'after' says to put letters next to each other.
'milk supplier' becomes 'teat' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'left' becomes 'L' (common abbreviation).
'owe' put after 'teat' is 'teatowe'.
'teatowe'+'l'='TEA-TOWEL'
Can you help me to learn more?
(Other definitions for tea towel that I've seen before include "kitchenalia" , "Cloth for wiping up" , "Kitchen cloth" , "Cloth for drying washed dishes" , "Wee total (anag) - drier" .)
