thank you for calling
with out a war to fight and rebels to destroy, TK4082 had to use his best asset in his new line of work...his voice. Being all stormtroopers are clones, they are ideal for a call center since everyone who calls in thinks they are talking to the same person.
What he wouldn't give to hold a blaster to his head instead...
Lord Vader was never one to be courteous to inferior beings.
