Help Is On The Way!

My friend was on duty in the main lab on a quiet afternoon. He noticed a young woman sitting in front of one of the computer workstations with her arms crossed across her chest and staring at the screen. After about 15 minutes he noticed that she was still in the same position only now she was impatiently tapping her foot. He asked if she needed help and she replied, "It's about time! I pushed the F1 button over twenty minutes ago!"
