I don’t feel it’s necessary for anything really, as long as the person is efficient.
On the flip side, any given time I’m at home, I have the radio on (CBC radio 2) - they have the news on every hour, on the hour and most often the newscaster is this guy Tim (something... I can never make out his last name). It’s never quite the same report obviously as there will be updates. But the guy messes up at least once in every single report, each hour, whether it’s someone’s name, fumbles on words, or goes: uhh, uhmmm, uh... I find it amazing that he hasn’t been thanked for his services. It’s appalling.
The funny part is, at the end of each newscast he finishes with: “And this is the world this hour, I’m Tim...”, and always seems to say that phrase with great comfort and immense relief that he’s finally done. I always have a visual of him sweating like crazy...
