Troubling to include a bit of tea in the food and drink provided (8)
I believe the answer is:
catering
'the food and drink provided' is the definition.
I can't judge whether this definition defines the answer.
'troubling to include a bit of tea' is the wordplay.
'troubling' becomes 'cering' (I can't justify this - if you can you should believe this answer much more).
'to include' is an insertion indicator.
'bit of' suggests taking the first letters.
The first letter of 'tea' is 't'.
'a'+'t'='at'
'cering' enclosing 'at' is 'CATERING'.
'in' is the link.
Can you help me to learn more?
(Other definitions for catering that I've seen before include "Providing food and drink" , "Supplying food and drink" , "provision of food" , "The supplying of meals" , "Making allowances" .)
