" A whiff of brine, a swank trestle adumbrant, Loading Only No Standing, 14th & 10th—this was Tetration’s NY HQ. I went through the doors and stood facing anything but the street, until a Tetbot treaded over to make inquiries. I stood behind a rubberplant. The Tetbot reversed and treaded after me. It was a clownwigged trashcan that barely reached my lowest hanging ball yet without compunction it was demanding my credentials: Tetrateer? or Tetguest? "
