I saw window cleaners at Male airport at the Maldives when we landed. I couldn't believe I travelled all that way and that was the first thing I saw. For the novelty factor, I asked if I could clean a few windows. They obliged which was a great memory!
At the hotel in Egypt, some hotel staff had a huge A-frame ladder, with one side going higher than the other. The lowest side was about 3 storeys, the highest side was about 5. I had never seen anything like what happened. He climbed up the 3 storey side, did what he could reach and to save time moving the ladder, climbed to the apex of the ladder and climbed around the outside of the ladder onto the 5 storey side and kept going up the ladder on that side! It was very dangerous, but strangely exciting to watch too!
