So some white? US guy calls and after I say hello, he says "Good afternoon, how are you?"  It is none of his business but I should have said "I am dying of cancer."  I hit the fax machine button and he hangs up and calls right back.  I answer and say nothing but just listen.  I hear multiple people in the background speaking presumably on the phone.  One woman mentions something about a package.  I just keep listening for about 2 minutes and he finally hangs up.  Try to waste as much of their time as possible.,  You might be saving someone else a lot of time and money.
