I work tech support, and my particular department has certain hours. It really gets on my nerves and others I am sure when a customer calls in with about 5 minutes or less till closing time with a complicated issue (most of the time) that keeps the person past closing time. Often, those who call in, it is often obvious they could have called sooner and many admit that they didn't get around to it. I give SS bonus points to those who demand certain things to be done very late in the day when their request may not be processed until the next day as not all of us have access to certain tools then proceed to have fits when we explain. I do not mind a call a few minutes before closing time for a very simple request though.
Reminds me of my tech support days. I was working 3-11 shift, but stuck around to take 'one last call' at 11 as the incoming shift was getting settled in (since we shared workstations between shifts, there was always a little chaos at shift change). The woman on the phone was having a hard time uploading a new web page. She was using a standard ftp program (ftp is the method used to transfer files to/from the internet), so I tried it several times and had no problem. So I started walking her through the settings on her computer.
Hillia: Now, where is says 'destination', do you see this number? 220.127.116.11?
Hillia: and in 'username', does it say 'CustomerName'?
Hillia: and in 'password', are you typing 'CustomerPassword'?
She can't get it to work. I go through the info again and again, having her check for spaces, cap locks, etc, and while I can move files with no problem, she cannot. After fifteen minutes of this, she says, 'Oh! In 'Destination', should it say 123..111.11.1?' Remember that she has confirmed to me no less than 5 or 6 times that that is what is entered in that field. She'd been totally ignoring all of my questions the whole time, just saying 'yes...yes...yes' every time. Even when I asked her to read back what her screen said, she just repeated what I had told her rather than actually reading the screen.
