Man phoned twice for people who either don't exist or work at another location, then wanted to know their telephone numbers.  I asked the purpose of his inquiry, and he said, "It's a sales call."  Of course it is!  What else would it be?  I advised that we don't give out this information.  The first time, I also mentioned Purchasing, and he hung up before I could transfer him there.  On the second occasion, I hung up.
