What is the experience of transiting through Doha Airport like?

Previously, when transiting through the Middle East, I mostly chose Dubai, but this time I found Qatar to be a good option as well. If it's just for a few hours, you can stroll around the airport. The rich have planted the largest indoor garden there, reminiscent of the Singapore indoor botanical gardens, and there are even transit passengers camping in the indoor forest . Another spot to check out is the Lamp Bear, which, I heard, cost the rich six million dollars . Although it's indeed very large, I can't see why it's so expensive; maybe the rich just wanted to spend money... Additionally, the airport has a monorail, which is different from the one at Pudong Airport that shuttles between terminals. This monorail is purely for those who don't want to walk too much. Apart from the numerous duty-free luxury shops, there's even a duty-free shop for sports cars, which I don't quite understand. How do you take it home after buying it? Well, just cover it with a cloth, you're the richest in the world, as long as you're happy. Actually, Doha Airport is very close to the city center of Doha, so if you have a day or two for transit, it's also nice to take a tour of the city, especially since it's visa-free. This time, on my way back from France to my home country, I stayed in Doha for two days, which allowed me to find cheaper tickets and also add another country to my list, which was quite nice.
