The room was clinical. No distractions some said. Others thought it was just a hangover from when researchers thought of themselves as scientists. There was the mirror of course, full length of one wall. Some still went up really close to see if they could see through it like they did on TV.

Like anxious parents at the school gate they reluctantly plugged their AI shopping avatars in and left the room.
