I wonder if young Chinese tourists behave like that at buffets? I can only recall seeing older tourists fighting over food. The young have grown up in relatively prosperous times (thanks, comrade president Xi!) and don't know about earlier famines. They haven't had to literally fight for survival like their elders.
Mind you, it's not just food they fight over. I've seen elderly Chinese women actually fighting over handbags at Louis Vuitton and watched as the staff stood back and cowered in disgust and horror, waiting for the police to arrive. Their husbands were just sitting down chatting, totally ignoring the mayhem. They'd seen it all before. Is it because so many Chinese are now part of the nouveau riche?
And of course, I was really pissed off when the handbag I was after was unceremoniously ripped from my hot little hands! Damn! It was a perfect match for my shoes. Lol
