That is 100% true. I have worked at best buy Part time for 5 years. You wouldent even believe the people that try and be a moble installer. It crazy Its amazing how they hire the kids with no tools,no experance and couldent take apart a neon to change a deck, its crazy.
I would say stay away from them unless you know someone there.
I wouldent trust to many people to cut into my car.
