Lot of manufacturing companies down the road in Laem Chabang that employers foreigners.
Maybe he was working the 8pm to 5am shift (a shift we have at my place of employment), can easily do Laem Chabang to Khao Talo in 30 mins.
My bad... met many great peeps from Scotland, none had the same stale piss aroma like those from England so I guess wrongly assumed they were not Brits......
