I was helping a user purchase a laptop. This user (at the time) had a personal issue with wine and would become sufficiently incapacitated that reasonable would could not happen. This user wanted a laptop, so I took the requirements and acquired a Win7 laptop that could do everything requested. I stopped by the user's domicile one evening to make sure things were working for the user.
The user was already incapacitated and complaining (loudly) the new Win7 would not work as wanted. I replied the laptop meets all the user's requirements. The used replied angrily to me the laptop "doesn't meet the stupid requirement."
I decided it was a good time to leave.
