I was thinking of the possibility that the uncle bought from some roadside stall that sells these tickets. Those tickets could be fake. Thought of this because he said he cannot recall where exactly did he bought it...
And why did he go to two outlets at two different parts of Singapore? A bit funny leh...
Remember about the Singaporean who bought a supposely winning 4D ticket in Bali from some Indon, who claim he cannot enter Singapore to collect winnings due to immigration, and then the poor Singaporean came back, tried to claim and then it was proved the ticket was a fake.
Third point, why did he take so long to collect his $30? Small sum, yes...but my dad will also collect <$10 of football winnings in the next available day.

Just my $0.02.
