Bob visited Lucia in Penang, the Tong Sampah Pearl of the Orient, together with his mates Irene and Mini. Upon arrival in Penang, they flagged down a trickshaw, and went their way off to Love Lane.

They checked into the presidential suite with jacuzzi in Lovers’ Inn and Health Spa, for the rate of RM 3000 per night.

As they were too eager to enter the room, they didn’t bother to pay at the counter. Instead, each of them took out RM 1000, paid the amount in cash to Menj, the conscierge who showed them the room, and let the conscierge bring the cash to counter.

At the counter, Lyn the cashier being kind and gracious, decided to offer them a discount. Thus she kept just RM 2500 and gave the remaining RM 500 to Menj, asking him to return it to Bob and company.

Menj thought that there’s no way RM 500 can be divided completely among the three, thus, evil Menj decided to pocket RM 200, and just give back RM 100 to each of Bob, Irene and Mini, and he did just that. Bob and company were very happy that they had a discount, and each of them happily put RM 100 back into their wallet.

Each of Bob, Irene and Mini had forked out RM 1000 and took RM 100 back, meaning that they have paid RM 900 each, or RM 2700 altogether. Add that to the RM 200 that Menj has pocketed without permission, it was still only RM 2900. So the question now, where did the remaining RM 100 go ?
