Petai is a bean with a strong smell and flavour, and it can still be smelled in one's urine a couple of days after consumption. It's devilishly expensive because every pod contains just a few beans. I paid SGD2.80 for 100g, and that's cheap for petai.

As a Singaporean I hear 'oarfish' and think 'black fish'.

Upfront payment leads to all sorts of unhappiness, like the time I bought a 5-dollar offering pack at the Jade Emperor temple and an hour after accidentally ordered tea with sugar instead of without.

Time to go to 济正宫 to 还愿 (huan yuan, give a donation to thank the deity for wish fulfilment). In Chinese folk religion, a lot of deities operate on a ‘no win, no fee’ basis.

Subsequently I met people whose office locations contained words like ‘Marina’ but the only meeting to come to fruition was the one at an office in Ayer Rajah - the only one that literally had ‘water’ in its name. Ayer Rajah is a Malay name that literally means ‘King’s Water’.
