I've assumed for a long time that fares on rapit transit systems like the subway ot the BART should obey the triangle inequality: going from A to C directly shouldn't cost more than going from A to B, leaving the system, and then coming back in to go from B to C.

But now I wonder why I ever thought this. A short, direct route is a valuable thing, and a passenger might be willing to pay a premium for it.

Or to make the difference even clearer, suppose, that the route from A to C via B uses an old, grungy, low-speed service, and the direct route is fast and clean. You might be willing to pay more for the direct route.

Gitlab is having a one-day mini-conference in Brooklyn.

To send one person costs $499.

To send two people costs $998.

To send three people costs $1497.

To send 4 people costs $996.

You can send six people for the same cost as sending three, five for less than that.

Someone is not thinking about what they are doing.

Stuff like this really bugs me. It's not hard to get right. And it should be familiar to everyone how to get it right, because it's the way federal income tax works.
