Staring at the CEO

I wash the windows in a 6-story building as part of my janitorial job and there were times when I either rappelled down from the roof or used ladders to clean them. One day while cleaning the executive floor windows, I looked in and saw the CEO inhaling something in his office with the lights off. We made eye contact for a few seconds then I continued to do my job as if I had never seen him. He tipped me $200 that day.
