Got a call from this guy at the office. Came up on the caller ID as "Wireless Caller". When I answered, there was dead air for a second, then I heard a click noise, like you hear when telemarketers call sometimes. The man was very gruff and asked for my boss by name. I began to tell him he was out of the office today when he just hung up on me mid-sentence. Very rude and obviously someone we don't care to hear from again. I get the hang up a lot from telemarketers when I tell them the owner or boss is not in.
