As my seat is right next to the Premium section, I always have tourists sitting to the right. Today I had three Sonny fans in my row, four in the row behind and another two in the row in front. One woman videoed the whole game on her phone on a selfie stick, the others had no interest in the game, apart from when Sonny was on the ball, so they weren't very animated! So your point about him being played to pull in his countrymen is quite valid, especially as they nearly all spend a small fortune in the shop.
And I'm with you re half & half scarves for any PL games, an abomination and part of what's wrong with the modern game.
