Spin Crowd publicist Simon Huck has had enough.

On Sunday's finale, boss Jonathan Cheban makes fun of his bowtie in front of Hills star Stephanie Pratt ("Pee Wee Herman," Cheban calls him) and then refuses to tell Huck whether he'll make him a partner in their L.A-based firm.

"There's no way I can continue staying here in the position I'm in now," a teary-eyed Huck says (see video above). "...We've had the most amazing seven years, but I'm not going to work here any more."

He then storms out of the office, leaving his coworkers speechless.

The season finale of Spin Crowd airs Sunday at 10:30 p.m. (EST) on E!
