Attending hotel, cheat gets beating (6)
I believe the answer is:
athrob
'beating' is the definition.
(I've seen this before)
'attending hotel cheat' is the wordplay.
'attending' becomes 'at' (e.g. at school means attending school).
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'cheat' becomes 'rob' (robbing is a kind of cheating).
'at'+'h'+'rob'='ATHROB'
'gets' is the link.
(Other definitions for athrob that I've seen before include "Pulsating" , "all of a twitter" , "Pulsing" , "beating" .)
