I have no proof of this, but I suspect that Ken Kaplan was probably drunk when he did this. If so, he’d better damn well be a senior partner at Gersh, because talent agencies are a cutthroat business; high level clients are very difficult to acquire and that loss, coupled with the unprofessionalism, WILL have some negative consequences for the firm - some that they’ll never even know about.
I was thinking the same thing: Drunk e-mailing on a holiday, yeah, that’ll end well.
