I went into an office one day and the receiptionist was busy doing everything by hand even though she had a computer. She told me she had to call a service technician because her computer won't work. She tried to print something earlier and the computer locked up. I set down by her printer then noticed that the printer was turned off. So I turned it on and everything was working again. I should have asked her for the $100.00 service charge, but I didn't.
