I called late Friday afternoon because of a leaking ice maker/water dispenser line on my refrigerator... he offered me 2 time slots for the next say, a Saturday! The young man showed up, with a pre-call alerting me to his coming arrival. He was polite, neatly groomed, and efficient. He quickly determined it was parts of the LG refrigerator at fault, not the plumbing/feed line from the wall. He told me how to fix it, which parts to buy, and where, and how to install them. I asked him what his fee was, he said probably no charge, called his boss to advocate on my behalf as a non-issue 5 minute visit, and, shazam, a no-charge professional plumber visit, on time, on a Saturday, and by a gentleman who was a compliment to his company.
