What a myopic follow-up to what was originally a myopic blog post. Of course the denominations are a result of trying to minimize change for people who pay in cash. And tons of people pay in cash, especially since a lot of lower-income people rely on public transit. Getting cash into and out of a credit card is not cost-free for people who might not have checking accounts, get paid in cash, etc. The author needs to get out of whatever bubble he's living in.
