Food and drink as a travelling expense? (4)
I believe the answer is:
fare
This clue might be a double definition.
'food and drink' is the first definition.
(thesaurus)
'a travelling expense?' is the second definition.
'fare' can be an answer for 'expense?' (fare is a kind of expense). I'm not certain of the 'a travelling' bit.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for fare that I've seen before include "Cost of travel" , "Transport charge" , "Food for the table" , "Range of food; travel" , "Food, or price of bus ticket" .)
