My company was hired to install new equipment at a bank. I had to adjust the printing on the customers' receipts. Weeks passed and my manager sent me back out to fix the printing alignment. A few more weeks passed and the customer called in a tirade that the printing was out of alignment again. He wanted the defective equipment replaced and didn't want to pay some of his bill. I was sent out again.
This time, I took a close look at the customer receipts and noticed that they felt like regular colored paper and had guide lines. Come to find out that they printed their own blank receipts and cut them. They were all different sizes. When I pointed this out to the customer, he couldn't understand why they still wouldn't line up. - David L.
