some friends who have travelled overseas - seems like everyone has travelled to other countries - marvelled at the trust or honour system practised in some of the developed countries. the system could be used for payment of newspapers, farm produce or even to pay for train rides.

you help yourself to the day's newspaper and drop the payment into a container. in melbourne -where i visit quite often and am now at - for example, not all the train stations have turnstiles. this means that a person need not have a valid ticket to board the train. in some outlying, rural areas in australia, the farmers just leave their produce at an unmanned stall by the roadside. you pick up what you want, weigh the stuff and leave your money in the honesty box.
of course on the train, once in a while you have ticket inspectors boarding it to check your tickets but so far, i have encountered them once on my so many trips on the melbourne train. if you do not have a ticket or if you under-pay, then you will be slapped with a penalty.
come to think of it, the collection of baggage at most airports is also based on a trust system. although you have the tabs issued by the airline, these are seldom or never used to check against the stickers/tabs on your bags. very often, when waiting to collect my bags, i worry about them being mistakenly taken by someone else.
in singapore, some toilets at food centres, like the one at sembawang hills estate, has this sytem in place. a coin collection box is placed outside each of the entrances to the men's toilet and the women's toilet. i find it interesting to observe the users to find out if they will be honest enough to drop their 10 cents into the box when no one is around. it will also be interesting to find out if more men or women do the honest thing.

the other day, i stood outside the toilet at bukit timah 7th mile food centre to make my observations. for the ten minutes that i kept watch, about 8 persons used the toilets but none make any payment. some either did not see the tin or they did not see any person sitting at the table, behind the tin.
i asked a friend: do you drop money into the tin when no one is around to check on you? "sure," he said, "that small amount goes to the attendant's earning for keeping the toilets clean." obviously, a lot of people do not see it that way.
so, it does not seem that the trust system will work in singapore, yet.
