You're not kidding. I recently stopped at the grocery store to pick up a few items. The total for my stuff came to $5.61. I handed six dollars to the clerk (age 20 or so), and she entered it in the register. It displayed 39 cents change.
Then I remembered that I had some pennies, so I pulled one out and said, "Here's a penny." Very apologetically, she said, "I'm sorry, I already punched in six dollars." I said, "That's okay, just give me 40 cents." This was incomprehensible to her, and she proceeded to count out 39 cents and handed it to me.
Just think -- she's a voter.
