Why does everyone in my parents generation and above not finish their hot drinks?

I am 31, and my parents, in-laws, grandparents etc. always leave a mouthful on their tea or coffee. I know I make a fantastic coffee and my tea is probably just as good. But it’s not just at our house, they do the same with their own drinks when we visit. This also includes their friends, so it is not just limited to my wife and I’s family. Is this a generational thing? Is there a reason for it?
