This takes "don't you know who I am?" to a whole new level.

While getting his hair cut in a Brixton, Floyd Mayweather surely came across a whole load of fans who wanted a minute to chat with the boxer, but he was more interested in talking to one Jamaican woman who had never heard of him.

As the highest paid athlete in sports, he was incredulous, and as the conversation continued, he eventually demanded that she Google him so that she would figure it out. She didn't seem to care too much about it. The video contains some NSFW language...

Being Jamaican, she did know who Usain Bolt is, which was at least something that made Usain himself happy.
