I ran today to the supermarket, later in the day we had our boiler in bathroom repaired, and had some electrical interventions on switch done. Man who has done that gave me some very professional answers on my few questions, and he did not charge much money for his work. So, he impressed me both for being extremely well educated (unlike many others) and for being modest. In fact I wanted to pay to him about 70% more than he asked for, but he just refused. It is very nice to see that such kind of people still exist.
