'patron' is the definition.
(I've seen this before)

'club let in drunk' is the wordplay.
'club' becomes 'c' (this might be a standard abbreviation I've not previously seen).
'drunk' indicates anagramming the letters.
'let'+'in'='letin'
'letin' anagrammed gives 'lient'.
'c'+'lient'='CLIENT'

Can you help me to learn more?

(Other definitions for client that I've seen before include "One represented by lawyer" , "Customer - dependant" , "Person represented by lawyer" , "Computer program" , "Employer of professional" .)
