That's how you perceived it because seemingly like this whole nation we want stuff to offend us. He knew who Danny was, he is a Liverpool fan ffs he might not have known her name and used it as a way of speaking to her. She was confrontational, 100% if something that isn't really that offensive offends you then I think you should tell them reasonably and give them chance to rectify it. Don't snap saying "don't call me darling" her job that day was talking to the general public, at least address them correctly. I will repeat again, if it offended her she only had to say sorry, do you mind not talking like that. She called him love back instantly too, oh no how offensive.
