My anecdotal sampling of orders at a coffee shop says it is common.

Coffee shops are not representative of everyone's routine coffee consumption.

By my anecdotal sampling a good portion of the population would never pay coffee shop prices for what they drink daily to function.

When I buy fivebucks coffee, sure I get a sweet drink.

But 99% of my consumption is my own cold brew. No sugar, brewed very strong, and then with just enough milk to bring out the flavor.

what city is your fivebucks in? It’s like sevenbucks in my city now

:D Yah, it's more like sevenbucks now here, too. That tells you how frequently I consume it...

Plus tips ;)

I rarely buy coffee at a shop and make at home. Even at the shop, I'm the person who gets drip coffee, black.

The fact that they have a big pot tells me there are others who get drip coffee.

Depends what country. In Australia I’ve not seen anyone ever put sugar in coffee. I’d say the vast majority order a flat white which is an espresso with foamed milk, no added sugar, and the rest get “an espresso” which is just a raw shot with nothing added.
