No I understand perfectly well. What I find amazing is the dedication to extracting potentially a little more money from people who may buy one extra cola rather than allowing a refill when the production cost is next to 0, but leaves a more satisfied, and likely return, customer. Practices like this are likely to turn people off. The fact that they think they can do something like this just displays how much of a monopoly/duopoly this company actually knows it enjoys. Where else will their customers turn? There's nowhere to turn. So gouge them.
