Embarrassed For Him.....Not Really

Have posted this before so apologies for repeating myself if it was on this board, around 2015 was in Amsterdam on a stag do, stumbled across a sports bar when Dortmund were playing someone else in possibly a CL final. There was a Swiss guy actively supporting Dortmund and a f**king clown in a Man U shirt ripping this piss out of this bloke who was a complete stranger - ‘How can you support a team, that’s not even from you’re country!’ He berated this poor fella in his strong Brizzle accent.
I went outside for a smoke and saw the wurzel and said to him ‘you’ve got some front, how the f**k can you wear that shirt being from Brizzle?’
He was genuinely shocked and finally said ‘well my dad supported them, didn’t he?!’

I feel such a fool
