You are at a market in Australia: The bill is 29.75 Australians have long done away with their pennies, they are expensive to produce, they have little value and clutter the purse. So the bill is 29.75. They ROUND UP to 30. You pay 30. Next time when the bill is 29.49, you pay 29. Fair
BEFORE YOU ROUND UP OR DOWN YOU HAVE TO HAVE A NUMBER.
There are many scheduled WILD HORSE ROUND UPS (with consequent removal)-Yet we do not know the numbers.
And when we know the numbers we have to come to an agreement for improvement.
