Hearing her quaver “Oh, Rob!” and “Oh, Mr. Grant” used to make me smile.
No. I don’t I’ve encountered a voice yet that would put me off. It’s not even a consideration of mine.
In my case, what I wouldn’t be able to take re. accent/dialect is one of those people who can’t rephrase, define, or even just grab a piece of paper and write it down. If you pronounce “good morning” as “aurrrghng”, yelling it will not make it understandable, it will get an ambulance called.
