A lab supervisor was on duty in the university’s computer lab on a quiet afternoon. He noticed a young woman sitting in front of one of the workstations with her arms crossed across her chest and staring at the screen.
After about ten minutes he noticed that she was still in the same position only now she was impatiently tapping her foot. He went up to her and asked if she needed help; she turned to him and replied, “well, it’s about time! I pushed the HELP button over fifteen minutes ago!”
