There is a larger asian population now, and the market is just adjusting. I like iced coffee too. Picked up a taste for it in Japan.
Asia? I drank it right at home here when I was a kid. However, I do remember some waitresses treating me like a weirdo for ordering iced coffee. I would have to explain to them to just pour coffee over ice in a glass and add cream and sugar. They would do it but they didn’t look comfortable doing it.
