yeah, sugar water is totally what people are going for when they get a costco hot dog.
Also, it is not possible to buy the hot dog without a soda. So really, people are going for the soda when they get the hot dog, whether they want it or not.
Also, I've bought the hot dog and forgone the soda.
That's why I have percentages for both the dog alone and the combo.
My original point is that by changing what metric and how much of the combo you look at the calculated loss can vary significantly: over an order of magnitude difference between the dog-only volume loss and the refilled drink calorie loss.
lies, damned lies, and statistics.
The option to get water is a meaningless observation that doesn't invalidate the assessment of what you get for the money.
