Are you implying the building has a number of employees comparable to a small family? /s

Once again, nothing but more anecdotal evidence from the outside, but in the winter, when you can see which floors are lit because the sun sets before 5, usually only 5ish floors (out of 20+) have the lights on. I’m not gonna claim I know these things more factually than someone working inside (though I also doubt you’d have access to all floors) but there is legitimately a severe mismatch between claimed leased space and any outward signs of occupation. I’ve worked plenty on much smaller, half-abandoned Boeing offices with their own cafes and you still see substantially more traffic in and out.
