An Elevator Puzzle From Real Life
1. When traveling from the lobby to my office, only twice does the display read an actual number. The first is 7. Three floors later, it reads 17.
2. My floor is next.
Question 1: What floor do I work on?
Question 2: At two points in this journey (including on the two floors between 7 and 17), the elevator rider is shown a pair of back-to-back non-number symbols that are exactly the same for two consecutive floors. What are those symbols?
Question 3: For that matter, which parts of the 8 are burned out?
