S20E08 - 3rd Filmed Task Question

>!Why were there blue words? I've only watched once, so maybe there's more clear info when I rewatch.!<

>!There were the blue p, t, and o on the sign. People speculated it could mean Please Turn Over. I think maybe Paid Time Off, as the most common meaning of that acronym to my ears, meaning that it behooves you to quit.!<

>!But then words showed up in blue. And from what I could tell, they were words with p, t, or o in them. Maybe just an editing quirk?!<

Thank you for your time. Anyway, all-timer ep in my book, from very beginning, to very end.
