You know, i bought this piece of cheese cake 2 years ago @ $2.00 at a bakery.
After buying it, i realized that the cashier charged me wrongly.
There's suppose to be a 50% off the cheese cake.

However, i did not tell the cashier about the wrong charges at that point of time.
Instead, i decided to wait till 2 years later, go back to the same bakery and make a fuss about the damn piece of cheese cake which i bought 2 years ago.

"i want a refund of $1.00 for the damn cheese cake i bought 2 years ago. LOOK HERE'S MY RECEIPT FROM 2 YEARS BACK!"

welcome to Singapore.
