Lol, I might steal that clip in the future. I don't really begrudge anyone who does those things - we're all involved in one massive prisoners dilemma of sorts whereby we each take actions that makes us a little more $$ while hurting other regs. - sometimes even to a group negative.
Even when someone is taking actions to hurt their own $$ (and that of other regs), it's not always black-and-white, and there's reasons other than $$ why people play the games they do. Certainly can be frustrating though, like the realities of many/most small businesses.
