Waiting on a Long Line

The checkout line at the hardware store was getting longer and longer as the clerk labored to get the new cash register to cooperate. At one point she wailed "Oh no, NOW what do I do? It just rang up sixty-four thousand, five hundred seventy four dollars in sales tax, on a ten-dollar sale!" Surprisingly, the customers in front of me didn't seem too upset by the delay. Some even chuckled sympathetically. It wasn't until I got near the front of the line that I saw the neatly hand-lettered sign in front of the register: WE ARE CURRENTLY DOING BATTLE WITH OUR NEW COMPUTER FOR CONTROL OF THE STORE --- WE APPRECIATE YOUR PATIENCE.
