Do customers expect too much from businesses these days?

I think customers do expect more these days, especially with how convenient shopping has become. The main reason is that apps like Taobao and Meituan have trained us to expect instant service and endless choices - if something's not perfect, we just return it or leave a bad review. For example, my uncle's restaurant in Shanghai gets complaints sometimes about small things like the temperature of the tea, which people wouldn't have noticed before. That said, I don't think it's all bad - higher expectations push businesses to improve their quality, like how my uncle keeps refining his signature dish based on customer feedback.
