It's too important to have things in writing these days, so even if they are close, I will email.
Oh don't get me wrong I will email so there is a paper trail of sorts, but the manager will not even speak as in general chit chat, you can sit there all day and try to spark up conversion, nothing, no reply or anything, if people are on hols and I am in on my own with the manager then most the time its earphones in and listening to music or going into other offices for conversation xD
