Person with loads of TVs sky boxes, DVD players and whatever other stuff they have nowadays. Music fanatic with big stereo in units and speakers which jeedplugs. Gaming systems. (All in every room) tropical fish tank. Loads are aerial type outlets for cat5 cables TV etc. I can see a tech nerd easily doing that!
I on the other hand put 5 double sockets in my kitchen and 5 in the bedroom and a concealed one for the TV. Electrician was having a meltdown saying I had an obsession with sockets. They all get used. Mine are all the same colours as the wall paper in the rooms and not silver- if only I'd thought of that, darn it. I could have had liafs and made them an art installation-feature😂
