Soda is dirt cheap once you have the machine since you're basically producing it in house, so no heavy skids to transport into the store, just a bag of syrup once every few days.
Bottled water needs to be trucked in and yeah, does actually cost more at the wholesale level in the end - at least the types of bottled water you see in a restaurant or store, not the flimsy bottled stuff you get in a case you buy for home/personal use.
That, and people who drink bottled water are often easily separated from their money so it constitutes easy money for establishments.
Yep, but people will pay $3 for a bottle of water since the "tap water is icky". Meanwhile, 50/50 odds that what's in their bottle is just filtered tapwater.
People don't connect the dots. I paced a guy in a big dually pickup truck (similar to what I was driving at the time) for about 15 kilometers across Highway 2 one day all the way from Ajax to Oshawa, he floored it at every green light only to screech to a stop at the next red light, while I simply drove the speed limit and ended up timing most of them so I barely had to slow down, if at all. We then ended up pulling into the same gas station and to opposite sides of the single diesel pump - he then struck up a conversation with me about how his truck used "soooooo much fuel", how he could only get 350 kilometers on 120L of diesel, and how he could barely afford to drive it anymore.
