Mr. Dunne, who is obsessed with golf, smokes cigars and stocks his office with cases of Diet Turbo Tea, a drink that claims to provide “anytime energy.” He has an intense, sometimes explosive personality. “He used to say, ‘If I am not yelling at you, and I am nice to you, it’s because I don’t like you,’ ” said a former colleague who asked not to be identified because his current firm does business with Sandler. Another Wall Street banker, who also asked not to be identified, interviewed for a position at Sandler in 2009. He asked Mr. Dunne for a guarantee, a set amount of money for one year, to come to the firm. “What will you guarantee me?” he recalled Mr. Dunne screaming. Mr. Dunne has given only a handful of guarantees during the 12 years he has run the firm. The next day, the banker said he received a call from Mr. Dunne, who apologized. “You got the full Jimmy,” the banker recalled Mr. Dunne saying sheepishly. [Dealbook]

    I just got the full Shazar – - wasted part of my life clicking on and reading his copy and past job. On the plus side, his seeming inability to write means that I didn't flush too much of my time down the toilet.

    I have a half Jimmy, a turbo tea and an apple for lunch every day that I'm not on the road.
