Hi all.  This is my first post here, as I just recently discovered this wonderous site.  I have been a barista for a few years now, and I've spent a lot of time on my own learning about the trade.  My question concerns what my boss is now telling me to do, and he thinks I should not be flushing the groupheads at all between shots, because it "screws up the temperature."  Now we have a 3 group Marzocco Linea, which is an obvious beast, so I have a hard time believing that a 1-2oz flush between shots will screw up the temperature.  We are pretty high volume, so there are times where we have 2 barista's on a 3 group and 2 group going all out, so I guess it's a lot of flushing, but enough to change the temperature, I don't know..  Plus I feel the flush also rinses out the screen, which is what I am going for.  I have fought many a battle about making espresso with my boss, so I am used to this.  I was hoping to get some feedback; is it necessary to flush the group between shots with this machine?  And will the flush between shots mess up the temperature?  Thanks for your help!
