I was stuck 24 hours in the airport in Singapore

What happens if you get stuck in the airport? obviously it depends from airport to airport, if this misfortune happens in the best airport in the world then you will not necessarily be bored or be forced to sleep on the floor.

I tried, voluntarily, to stay at the airport for 24h, I could have gone out and gone to a downtown hotel, but I decided not to go out and experience all that the airport has to offer departing and transit passengers.

All as a real bum, that is, trying to spend almost nothing.
