The entire industry is shifting to WFH. I can tell because of the beeps.

I swear in 1 out of every 5 or 6 calls to a customer service line I hear an intermittent beep go off every few seconds in the background. I used to think it was a call center thing. But then I realized it was a smoke alarm beep.

Not only is every customer service rep working from home now, but for some reason they'd rather deal with beeping than change their smoke alarm batteries.
