Busking at South Station, a T inspector told me I had to move to the posted location, because I would be in the way of traffic. The posted location is about six feet from where I was, but there's a big giant fan in it. The big giant fan wasn't on, but I'd be equally in the way of traffic (i.e. not-at-all) in either location.
So a couple days later, I did an experiment; I spent half my time in the posted location and half in my preferred location. I made as much in the first ten minutes in my preferred location as I did in the previous hour in the posted location. I don't know why, but I've found this to be true in the past as well.
Subway busking would be SO much easier if anybody were steering the ship; as it is, the Transit Realty Authority (better known as the TRA) and the Metropolitan Transit Authority (better known as the MTA) are levying a burdensome tax...no, wait...the TRA and the MBTA have each told me that Performer's Area signs are the other's responsibility, so most locations that are supposedly kosher to busk in don't have signs at all. Alewife and Back Bay have shiny new signs, but those are the only places I've seen those particular signs.
I also discovered that, according to the rules, T inspectors can take one's permit at any time for pretty much any reason, so I really have to stop arguing with them, no matter how politely. I have an issue with the fact that one person having a bad day can take away half my income on a whim, but this is the life I chose, innit?
