If you go to a train station to ride the train, then you should be able to purchase a ticket right there at the station. I would think that is a self-evident. And if you are eligible for a special fare discount, such as a senior or youth, then you should be able to purchase a discount pass at the station. I would think that is also self-evident. This is standard practice for almost any transit operator — except BART: This sticker is plastered to BART ticket fare machines — informing parents and seniors that they can’t buy discount train tickets at the station. Instead, one must either take time off from work to schlep down to a Clipper service center, or else fill out an “application“, mail it in along with a government ID — and then wait for 7 days for your train ticket to arrive by mail. Here we are in the technological center of the universe, where BART has spent tens of millions of dollars on ticket vending machines (not counting the hundreds of millions of dollars the MTC has spent on Clipper “smart” card technology). And yet something as simple as buying a discount kids or senior pass requires an application, identification check, and as much as 7 business days of processing. And for what — to make sure your kids aren’t on a terrorist watch list?
