This morning. Home improvement store. Checkout. Price plus tax $18.02. I paid cash with a $20 bill and wait, I have two pennies in my pocket. I hoped I get two dollar bills back. No, I got one dollar bill, 98 cents in coins plus my additional 2 pennies back. Asking her why she entered $20 instead of $20.02 for the amount rendered, she responded she was never taught to enter such odd amounts. I gave her all the coins back asking for a dollar bill. She put it on the counter and started counting them. It took her two attempts to find out that it was a dollar. No child left behind!

Great comment! I do it pretty much the same way. While I am thinking what the comment should say to me in 5 years, I usually get good insight what the code-approach should be to work best. When I work on my 5 year old code, I many times wish I would have thought the same way 5 years ago. :(
