There was a guy who worked for Blockbuster video. He found it to be a great but complicated job. One day he was at the register and a older man came in and asked if he could buy a phone card.

So the guy gave him a card, and he wrote him a check for 39.

80. He then told him that it was 20 cents short, so he gave him 2 dimes.

Unfortunitely when he typed this into the computer, he missed the period on the keyboard and it came up as 20 dollars. That night, the manager said that he was 19.80 short. The manager thought the guy had stolen it, so he fired him immediately. And the moral to this story is: "Guys get in trouble over missed periods."
