My washing machine was leaking water and so I asked Robert to take a look. After taking the time to carefully figure out the problem, he came back the next day with the proper parts to fix it. He even stayed longer to test out the machine thoroughly to make sure it was running properly.
What really impressed me was what happened afterwards.
The washer started leaking again, but much much less. I tried a few loads over the course of a couple weeks and finally gave in and asked robert to come back. After looking at it again, he noticed that there was actually two sources of leak, a major one which he fixed and the smaller one which he determined was not repairable.
He offered to give me back most of the money for the repair. I refused since at least he made my washer usable for the time being until I get it replaced. Finally we agreed to a smaller amount, for me to "take my family for a nice dinner", as he kindly put it.
This experience really left an impression on me. A truly honest and honorable professional with lots of integrity. Highly recommended.
