Pennies waste time. The average American wastes 2.4 hours a year handling pennies, or waiting for people who handle them. This statistic is the result of collecting a number of penny-handling related events , including the ubiquitous (无处不在)30-second period we sometimes spend waiting for someone who just has to dig through their pockets or purse to find that last cent so they can pay for something with exact change (probably so they don't get stuck with an more pennies).
