the.com/ticket booth

means A small enclosed stand, usually at the entrance to an event or venue, where tickets are sold.

from 'Ticket' traces back to French 'etiquet' or 'estiquette' — a little note or label stuck up as a notice (the same root that gives us 'etiquette,' the posted rules of conduct). By the 1700s 'ticket' meant a slip granting admission or passage. 'Booth' comes from Old Norse/Middle English roots meaning a temporary dwelling or stall — the same word behind market booths and voting booths. Push the two together and you get exactly what it sounds like: a little stall built to hand over your admission slip.
