I think that there is a right way and a wrong way to steam milk and also to be a customer. I hate to say it but both in this situation arent good examples of the right way. I realise youve got the s**ts Robusto and that youre obviously concerned about the bushfires but perhaps you might have handled this a little better.
Had I been on the receiving end of your righteous wrath, Robusto, I think I would have ignored your "instruction", seeing as I dont take to well to being spoken to in that fashion. I believe that people respond to postive instruction rather than negative and considering my background in sports coaching, I do know what Im talking about.
Maybe lessons learned from both sides here... ;)
And shout me down in flames if you dare :D...but I usually flush the portafiller from the grouphead and wipe dry. Usually too there is water dripping from the spouts but by the time Ive loaded and locked it in, the water has emptied out of the portafiller. Be thankful that they even bothered to clean it out. Most wouldnt.
