Deal with entertainment paid for by another (5)
I believe the answer is:
treat
I believe this is a double definition.
'deal with' is the first definition.
(synonyms)
'entertainment paid for by another' is the second definition.
(Other definitions for treat that I've seen before include "Give care to; surprise gift" , "Apply remedies" , "Pay for someone's food or drink or look after them medically" , "Minister - buy one a drink" , "Tend" .)
