Had a massive wind storm back around here in 2012..the service provider we worked for was so anal about working the day after it when nearly the whole area was out of power even most of the techs had no power. Just beyond me how companies can be like that. They came up with excuses to use our inverters we had running our laptops in the vans to run a drop cord to get a install done if need be.
Claude is right though - soon as people get power back on even if the house is still a wreck they will watch TV and forget all else.
I did installs where walls had huge holes in them or floors and they didn't care just wanted the TV to work.
People are both crazy and mind warped.
