Tom talked about this on a show once, where he's annoyed with the Improv Everywhere people who went to Best Buy and they all had blue shirts on, confusing the customers and making things more difficult for the employees. I agree with Tom. Do you (Improv Everywhere) really want to make the life of the person who works at Best Buy any harder? The kid that stocks the DVDs? The poor sap who has to drill together the security fixture so you can't steal the demo Wii-mote?
I don't know what to think of this. On the one hand, subtle reminders of the art in ordinary things is really great.
On the other hand, to pull this crap during weeknight rush hour when all I want to do is go home to my family and other responsibilities... I'd be pissed if as a result I was late picking up the kid, and out $20 or $30 bucks for the privilege to boot.
Sounds like I do know what I think. I think its no good.
