The chain of communication is getting better day by day. A tells B that we need some stuff, B tells C, C says D could buy it, so B asks D. D asks E to call F (that's me...) if A really needs stuff. F tells E to call G, because there was some confusion some weeks ago. E will get a mail from G that B already got that stuff. B will be confused. D will buy that thing, A will be happy, F will discover a spare thing, so that D did not need to buy it in the first place. And there was not alot of rejoicing.
