Woman named Gail called asking for our CEO by name, I asked if he knew why she was calling and she said "if he has a good memory" (red flag #1), then I asked what the call was regarding, "a financial matter" (red flag #2) and then whilst coaxing more detail out of her (after getting details ask a questions regarding the information they just gave you, this usually trips them up because they can't remember the fib and they end up divulging more of the truth) she said it was in regards to a possible mutual connection with (this is where they usual mumble or slur a name) "Common Cecil?" And then she threw in that this was "time sensitive"... which usually makes people hustle but for me this is just (red flag #3).. because quite frankly, the only person this is "time sensitive" to is you, I don't care, the only time I care about is my CEO's and not wasting it. So I basically talked her into telling me that she really had no legitimate reason for calling and bugging my CEO which leads us to her number now being in my special spreadsheet of numbers not to put through to anyone.  Not only do I have her companies phone number but I always try and get their direct line as well.
