This final note today, cribbed from our friend John Carney at CNBC.

John blogged today about a new dress code at Barclays — super-casual Friday, it’s called. Jeans: fine. T-shirts: fine. Even sneakers: also fine.

Not fine at all, though, with some of the old-timers. “I didn’t become an investment banker to dress like a perpetual teenager,” said a veteran of Lehman Brothers. Said another: “It’s ridiculous. Please make them stop. It’s like working at a start-up but without the IPO.”

Or, y’know, public radio.
