As for the "surprise visitor", IMO they should have used a little common sense and business etiquette, and called in advance to arrange contact. Would a reasonable person expect to be able to just show up at the door and gain an audience with whoever they wanted to talk to? They've got a business to run, and may have had a full schedule or been on business travel. Was there an expectation that they would bring business to a halt in order to entertain the surprise visitor?

Why don't you call down there and arrange a contact. Let any of us know what your response is. They don't answer e-mails and Cliff is always unavailable. You probably applauded the virtual SHM meeting as well. Busy running which business?
