yeah until that car mechanic or the guy who fixes your house says he fixed the problem only to find out a few days later the problem is not fixed. I had a car mechanic say he fixed my check engine light on my mercedes. I paid him 2k for it and was glad to do so as long as he fixed it. Turns out the check engine light came back on the next day. Now he wanted to do something else and wanted another 2k for it. it goes both ways.
