Sugar ratios

Purpose: One sugar is too sweet in a small coffee.

Experiment: I order a medium coffee with one sugar and it’s still too sweet. As liquid volume grows and sugar stays the same, net sweetness should decrease.
False.
I order an extra large coffee with one sugar, it was almost sweeter than the small.

Conclusion: They don’t know what the hell they’re doing.

Also, the new triple chocolate donut from Tim Hortons is horrible. This was the first time I’ve thrown out a half eaten donut.
