Sure. Then just say I’m mad because these water bottling companies get the water concessions for cheap (and I don’t), instead of some other made up reason that might be less honest but a more sympathetic argument.
Arguably the reason they bottle the water is because of the cheap concessions. Without those, their profit margins are a lot slimmer and maybe the industry is much smaller, leaving more water out of bottles.
They're selling the cheapest commodity in the world for more than the price of gasoline. Even with smaller margins they're still making money hand over fist.
