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 tell whether this 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 give a lot more credence to this answer).
'to include' means one lot of letters goes inside another.
'bit of' says to take the initial letters.
The initial letter of 'tea' is 't'.
'a'+'t'='at'
'cering' placed around '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" .)
