Client (8)
I believe the answer is:
customer
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">client</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that client can be written as customer)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for customer that I've seen before include "Shopper (or now rail passenger!)" , "Someone who pays for goods or services" , "'Buyer, client (8)'" , "The person who is said in business to be always right" , "Person paying for item or service" .)
