I am a contractor working for an agency that had just sent my main client to sensitivity training for a week. This woman was known for being difficult. My job was to build a travel reimbursement application. One day she calls me into her office needing to inform me of a program bug. She tells me that she wants to enter a departure time of 5:00pm on the 8th, and a return time of 12:00pm on the 8th, which to her is a 7 hour trip. I tell her that if she wants a 7 hour trip, she needs to enter a return time of 12:00am on the 9th. That of course, is completely out of the question. She keeps repeating to me that she wants a return time of midnight on the 8th. I told her that midnight on the 8th is not the last minute of the 8th, but in fact, is the first minute of the 9th. She yells at me at this point, asking me if "I think she's stupid". She then tells me that I'm a smart boy and can do it if I try. I tell her that I can't make the computer understand time travel. This is the statement that caused the curse words and name calling. I finally give in and tell her that I'll do it if she can get the approval from my boss. She agreed and I never heard anything about it again.
