WAS THERE A PROBLEM?

Observed today on the way to work from about .75 blocks' distance:

A man in what appeared to be a FedEx or Kinko's uniform (do they have uniforms?) yelling in what sounded like Vietnamese into a cellphone in a completely frantic, unhinged way that I'm finding truly difficult to describe, yet whose body language seemed to convey almost no urgency or panic. None of us walking past Sacramento and Davis this morning will ever know what that was about.
