Thingsthatgetonmytits#102 - someone phones you up to ask for some information, you give it to them but it then takes them 5 minutes to go and look for a pen and paper to write it down.
#103 People who ask for directions and then either 1) ask if there are any other routes or 2) ask if you are sure. Number 2 I normally answer that I am not Sure I am Chris! or say that George Bernard no longer works here!
Chap phones home yesterday inquiring about motor refurbs, Andrea tells him that I'm at work, he then promptly asks her if she's the one who makes the tea - he's lucky not to have been told where to stick his motors LOL
