Yep -- 14 years ago at Houston International. I missed my connection. From about 8 pm to 6:30 am, my home was the airport. I thought about an airport hotel, but I was a poor student, and I stood to gain only a few hours of sleep in a proper bed.

So, I found three seats in a row in the terminal and made them my bed. Unfortunately, the maintenance staff chose that night to replace the light bulbs in the ceiling near my "bed". I still recall the sight and sounds of loud equipment that propped workers up to the ceiling for the light bulb changes. It was pretty unpleasant.
