I know the current economic environment is causing folks some stress but...
Last week we had someone call in 15 minutes before his interview looking for directions. In the process, he was rude to our receptionist. He showed up 15 minutes past his time slot and was irate when we told him the VP of HR had gone on to another next meeting.
He demanded to speak with our VP and said he wasn't leaving until he did. Not sure why but I assume he wanted to air his grievances.
We called security and had him thrown out of the building.
