It’s true - at least in my nonscientific personal experience. Every time I go to Seattle I try and order a ginger ale in a restaurant/pub/bar, and they look at me like I’ve asked for a bowl of Qyxylix… Several times wait staff have offered to mix Sprite and Coke together to give me some sort of ersatz version. I have declined. A few have asked if I’m from the East coast, but I’m only from about a hundred miles north, in Vancouver.
Now I’ve had it on other jaunts to the US - California, New York, Connecticut even. So why Seattle?? Shouldn’t Canada Dry look into this?
