You're just not getting it like the other "Wipe your fanny" merchants. It isn't that people wanted a flag, although I know kids do take them home and I've seen plenty of adults do so too, some even going through the stands after full time to collect more. First it's the image it portrays of the club. The Leicester end looked fantastic, flags everywhere when they came out, ours looked empty and devoid of atmosphere. Secondly for a club of our wealth it's a tiny gesture in cost but it helps generate some atmosphere and looks great when the team's come out. It's a souvenir for kids who may be attending their first Wembley game. One of the most poignant moments of the FA cup final against Watford was when their end en mass started waving their flags at I think it was 5-0 down at that point. It looked fantastic and showed they were right behind their team even getting hammered in a showpiece game viewed around the world. Everyone in our end applauded them.
Yes it's a fairly new thing. I can't remember when it first started, it certainly wasn't there in 1976 against Newcastle when we made and took our own flags and banners. I don't remember it in the two finals against Spurs in 1981 either, nor the Gillingham play off final in 1999.
For me on Saturday it would have been a small gesture of thanks for making the effort. After a tough 18 months for many and if you didn't get a ticket in the ballot for the Everton game, it was the first match fans could attend since the cursed pandemic. Leicester did it, we didn't and as a result scored an own goal.
