Usually, when governments attempt to enforce the law, they typically use “sticks” and not “carrots”. In Taiwan, the government has come up with an ingenious way to encourage vendors to give receipts. On each sales receipt there is a lottery number. If the vendor “forgets” to give a receipt, the purchaser will ask for it. Why? It could be a winning lottery ticket!
Of course, a government lottery is still a lottery, so your chances of winning are low. Therefore, some people give their “receipt / lottery ticket” to charity. The photo below shows a couple of drop boxes that two charities have left outside a convenience store. You can find these near many businesses, so it is also an easy way to be generous.
