I believe you that it works, but I'm totally shocked at this... surely everyone just starts rounding up to .75? It will add up! You've literally blown my mind with this; how do people carry on like this? It's like you've just told me up is down and down is up, I just do not comprehend at all how people can use this system?
Seriously, I know that sounds sarcastic but it's just thrown my brain.
Of course, if you pay via credit card or bank card other electronic means, as more and more people do even for small amounts, you pay the exact price.
Ever notice how gas stations usually give prices out to 1/1000 of a dollar (e.g, $3.459/gal) even though our smallest currency denomination is for only 1/100 of a dollar?
It happens with sales tax, too. In Chicago, the tax on a $29.99 video game is $2.924025. We'd just round down to $2.92, and the government lets that odd 0.4025¢ slide. It doesn't really add up, because there's also cases where the tax owed is something like $2.925975 and gets rounded up to $2.93.
