I redeemed the free ticket and the npc showed me the list of chairs to choose from. After I clicked on the first one I wanted to go back and check out the other chairs before making a final decision on which chair I wanted, so I clicked "No", but that made the window close and when I redeemed the ticket again I got a random cash shop item. The instructions said I was able to see the chairs before I chose so I thought I could go back to the list instead of having the whole thing close on me.
Free Tickets you cannot choose what chairs you get as it’s a 1% chance to win one. You most likely clicked on the option to view available chairs via Tia or some sort since you can access them publicly without needing a ticket. You can only choose chairs if you won a forum event or something to that effect.
