Jibber Jabber

When a customer comes through the door and opens it's flap trap, all I hear is non-sensical jabbering. I've found the only way to get them to shut up is to get really technical, as fast as humanly possible. It also helps to be vague ad unhelpful and they'll just leave.All you have to do is say "It seems to be a fault with the PCI slot on your motherboard that may have damaged your modem, motherboard and other componants of the computer." It's complete bullshit, and is only used on annoying customers (all of them).
