In my local. Twice. Two different people, at that. One was loudly giving a "Hove, actually" style speech to someone so I asked him, the other recognised the club logo on a scarf (it was bloody freezing and I'd just come in).
On a funicular railway in Barcelona lat summer, i was wearing the stripes and a man started talking to me and he was also an albion fan.
Also at MGM studios in Florida a way years back
Gordon's Bay near Cape Town, in a bar, March this year. Bloke tapped me on the shoulder asked me where I was from, turned out he moved there from Brighton 20 years ago. Was reasonably clued up about Falmer etc.
At Ground Zero in New York in 2005 looking for Roberts name on the memorial wall & in the queue for the Atlantis log flume ride at Seaworld Orlando in 2002
I was in Cape Town in March...but that certainly wasn't me as I was only visiting.
I met two people from Brighton in a hut on the side of Mt Kinabalu in Malaysia a few years back, one said that he was an Albion fan, but neither were wearing the stripes. I also bumped into a couple wearing the stripes in a shopping centre in Glasgow, they said that they were on their honeymoon...which struck me as being a bit odd, but also that they would wear English football shirts in a place where they might have attracted the wrong sort of attention.
A few years ago in Menorca (Southampton cup final) went to the local for a few beers and football. Sat with a bunch of English, talking football and drinking beer- turns out there was 1 Villa, 1 Sunderland (Mackem an' proud!), 1 Evertonian and (including me) 3 Brighton! Now that felt unusual, rather than the usual 'who?' 'gayboys!' etc but 'Yeah, us too!'
Was waiting at a remote station to go to the WACA in Perth to watch the Ashes game wearing 'SKINT' shirt and the only other person there came up to me chanting 'SEAGULLS!....' he was from Whitehawk!
theres a little thing that goes on with swindon fans that when we travel away from uk to strange places we take a swindon shirt to give away on the condition that if anyone asks the wearer about the shirt they have to reply "i hate oxford".
so far shirts have been spotted in cameroon, manawa ferry driver in fiji, barman in mexico city etc etc.
My first day at uni, a random parent had just dropped his daughter off and was driving off wearing his Albion shirt. I was wearing mine and we both noticed each other and had a few minutes' chat. I met his daughter a few weeks later.....
Also at the Eiffel Tower that one summer a few years back that was just stupidly hot. Myself and family were standing in the queue sweating buckets with brother and myself both wearing Albion shirts. A couple of French guys (also brothers) working on the lifts noticed us and waved us into the staff lift - turns out their mum had lived in Brighton for 20 years and still did. Free admission and jumping a 90 minute queue, marvellous scenes.
haha, thats ace. football related queue jumping rocks, i have met a few ex pats off the swindon forum on my travels. bangkok, new zealand and hong kong to name a few, always strange talking about football in totally alien places.
