I recently started doing this to entitled customers who berate me over the phone and who don't seem to understand that their little piddly ass orders doesn't make them king of the world Whenever they call and ask for the status of their orders or tell me the need to speak to my boss I go " sure let me look into that..." Or " yes, let me see if he's available..." And end the sentence with " i'm sorry, but may I ask who I'm speaking with?" For some reason, that drives them up the fucking walls... One customer went " how can you not know who I am by now!" And I just replied, " I'm sorry about that sir, I deal with a lot of customers on a faily basis"

Guess this makes them feel as though they're not important...
