Rory McCann's mail reminded me of American ATM machines. In the Netherlands, if I want 20 euros, I type in '20'. In the US, if I want $20, for some reason I have to enter '2000' despite the fact that the least amount of money I can get from the machine is $10.
From my perspective, it would make the most amount of sense if 0.00 were
fixed and you started filling out the 10s spot, although I can understand why the Dutch machines make you start at the 1s. The American design, however, is just plain retarded.
