Singapore 2 Thailand 1...just don't ask me how

Mind you all, I am a Singaporean but the match last night between Singapore and Thailand stink. Singapore beat Thailand for the first time in 30 years but there was nothing to gloat about because Malaysian referee C. Ravichandran gave a penalty which quite frankly did not exist!
Somehow, the referee saw that Singapore striker Noh Alam Shah was pulled down in the box by Thai centre-back Niweat Siriwong in the 82th min. The Thai then staged a 15 mins walkout. What nonsense!
Every player on the pitch was turning to run down-field after the incident, there wasn't a single protest from anyone (including the Singapore players) for a penalty. Even in Singapore, there was hardly anyone who think it was a penalty. The morning papers in Singapore tried to say that the Thais should not have walked out. That may be true but hello! Why isn't anyone saying anything about the awarding of the penalty? A bad decision is a bad decision, why isn't anyone screaming kelong? Nonsense!
