At AV Specialists we do audio video installation in the Clearwater, Tampa at St. Petersburg, Florida area. As the owner of an AV design and installation business, I am often surprised by the amount of really bad workmanship I see in my travels. Sometimes it amazes me that contractors actually get paid when I see what their jobs look like.
It's not uncommon to see cables hanging from the TV instead of being neatly zip tied together. I also often see TV's that are not hung straight and you can obviously see that they are mounted on a tilt.
