I didn't know racism was so prevalent in England. It is sad that this woman had to write this kind of "Warning" In her own business. People can be so ignorant sometimes.
These idiots are so ignorant, what's wrong with a black person? To me nothing is wrong with that. I am fine with all races and I think they are good too. But the problem is that these racists need to study others on the inside (Which is the behavior and the attitude) and not from the outside which is the looks of them.
I am surprised that this occurred in England, where racial mixing has been around for hundreds of years since the colonisation era. I hope it's a localised incident, like much racism is.
