A businessman who gets it. Sergio left a more profitable job in a home that was uninhabited to fix my water line. He could have told me he was too busy, but didn't. Not only did he do that, his fix was an improvement over my previous installation - added a pipe union on his own to make future repairs, if necessary, easier. So, if anyone is familiar with Napoleon Hill, Sergio went the extra mile, and he did it because it was the right thing to do, not because he expected something for it, or because some inspector was looking over his shoulder. (Andrew Carnegie - in the early to mid 1900s - was Hill's mentor, so business mindsets have changed considerably - minor comment on today's state of affairs) He did the work well, quickly and at a fair price. Bravo! Needless to say, he's now my guy here in southern Arizona.
