I used to hate it at school when my French teacher called me “Rob-errrrrr”. I think this is just the same, but with less chance of a board rubber being thrown at you.
I reckon there’s a bit more to it though, if this guy’s so annoyed that he’s written a whole article about it. There’s probably half the population rolling their eyes wondering why this guy’s got this space on BBC news, but it’s not really about his name, is it - it’s about low level racism where people don’t make an effort to get his name right, just because he’s not got the same colour skin as them.
