Think the "display" was bad - pop down this week for the IRAoke in the Almondvale Suite with the Jock Stein Supporters Club, which has been taking place for Old Firm games, since the ticketing bans were introduced. Now that's tinpot.
I think you're getting your games mixed up. I sit the row behind "W" and there were none that I was aware of conspicuous or otherwise that day.Flow and the staff did a great job that day in keeping the infiltrators out.
"Skippy Sunday" was an entirely different matter.
They might have taken them down because it was either "postal or Collection" only. No QR codes or ability to print at home. Not sure if Dundee have an option to buy a ticket prior to the game - like Livi do.
