I ran into a weird situatoin at one point in my life. I was in an office where apparently it had become acceptable to shout out “WTF?” or “RTFM!” at a volume easily heard from a dozen or more feet away. The acronym was fine, but obviously the actual words behind those letters would not be. At the least, I saw no indication that saying “what the f**k?” in response to a surprising incident would have been acceptable, and I certainly hoped that it would not be in any professional environment.
I don’t really have anything else to say on the topic. But it was weird.
