this one still gets me to this day... i replaced all of the computers at a law firm once. it was done after hours. it took me all evening. i was proud when it was done. new desktops, new laptops, everything worked with their existing infrastructure, etc. i went to bed exhausted sometime after midnight. i got a phone call at 7am because a woman said he computer wouldn't work. i was freaking out because she was one of the partner's secretaries and had been there since time began. she was also a very nice lady that i always enjoyed talking to. so i quickly showered and rushed in there. i get there and one of the partners sees me in the hallway and essentially berates me because his secretary is unable to do her job and she has work to do. the issue was none of her desktop icons were in the order that they were previously in on her old computer she would start her day and go down the line of icons from far left top to bottom clicking on law program 1, law program 2, law program 3, email, internet. i don't remember the order i had them in. all i knew was that all of her law programs were there and automatically signed in like she requested and all data was there. i would have never thought she would be unable to use her computer because the icons were out of order. she panicked because icons were not where she wanted them to be and was literally unable to do her job. i think i learned very quickly right then and there that sometimes people panick and their brains shut off when it comes to technology and things they don't understand.
