If you want to really see someone get confused - go to a register that doesn't automatically tell the clerk how much change to give you, purchase something that costs $8.26, give the clerk $10.01 and see how long it takes to get the correct change! I hate pennies so if I can give them one penny so I don't end up getting 4 as part of my change I will, but it usually causes more trouble than it's worth! Our kids don't know the basics these days - I had a cousin who couldn't tell time on a regular watch - he only had digital clocks when growing up so had not a clue how to read a clock/watch with a regular non-digital display
