Sales booth (5)
I believe the answer is:
kiosk
'sales booth' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for kiosk that I've seen before include "Pavement shop" , "Newsstand - refreshment outlet" , "here's where to get tickets" , "Cubicle, booth" , "Roofed stall; telephone box" .)
