It was hot last week and my air conditioning was not working.
I looked in the Yellow Pages and called Steve's Heating and Cooling. Steve Ambrosini came out the next day, found the problem immediately and fixed it.
Since it only took him a few minutes he didn't charge me anything. He could have charged me whatever he wanted, but he didn't. I wanted Napa to know we have a good honest hard-working guy in our town.
