Guy providing drinks with energy (5)
I believe the answer is:
tease
'guy' is the definition.
(thesaurus)
'drinks with energy' is the wordplay.
'drinks' becomes 'teas' (tea is a kind of drink).
'with' says to put letters next to each other.
'energy' becomes 'e' (physics symbol as in E=mc2).
'teas'+'e'='TEASE'
'providing' acts as a link.
(Other definitions for tease that I've seen before include "Make fun of; comb wool" , "Poke fun at" , "Deride" , "Taunt or bait" , "Rag" .)
