A traveller in company? (3)
I believe the answer is:
rep
'a traveller' is the definition.
(travel company worker)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for rep that I've seen before include "Repertory theatre" , "Travelling salesman" , "Stuff" , "Theatre; fabric; salesman" , "Salesperson" .)
