Complacency

So I'm on the SL, going to the Courthouse stop.
I don't know if you've seen this particular stop, but it's pretty nice.
In fact, it's TOO NICE. The MBTA probably could've save a few million if this station wasn't so ornate.
I know, I know, I'm known for saying that MBTA architecture is of the Soviet style, but this is ridiculous.
The station is set on 2 levels.
You come in the headhouse, which is a nice glass and steel number, and into a cavernous concourse area. Really, it's like an airport in there. It's got to be 200 yards long, and is COMPLETELY EMPTY, save for the token booths and the turnstyles. Why bother with such a design if that's not even where people would wait for the bus? Anyway...
So I get off of the bus/train thing and go up to the concourse, where I notice that the turning barrier bit of one of the turnstyles is missing.
I walk through and go to the token taker to let her know.
Mind you, this station is about 6 months old, is rarely used, and shouldn't be breaking down already.
So I tell the woman about the broken turnstyle. The conversation went a bit like this:

TA: Hi. Did you know that there isn't a barrier on the turnstyle over there?

MBTA: Yeah. It's broken.

TA: I assumed that.

MBTA: I've actually got the piece right here.

TA: But who is stopping people from just walking through?

MBTA: Uhhh. Well, there are cameras.

Okey dokey.
