Which is why I find the continuing push-the-envelope behavior by some here both reckless and short-sighted. Make changes when appropriate only if they are really needed, better yet with little or no human intervention, and only when they are consistent with the fare rules, not for the purpose of tinkering around the margins. It shouldn’t be a contest to see who can push DL/KL/AF’s patience and goodwill too far before ruining things for everybody.
