Victoria Beckham. I know many people who have said they don't like her, but can't put their finger on why.
Well, my ex-flatmate worked in Gucci several years ago. The shop was closed early and she was told to stand at the till and keep quiet. Victoria came in with an assistant. The Senior shop girl, who dared to ask her when she picked up a garment if she wanted it put in the changing room, was ignored. Instead, Victoria turned to her assistant and whispered something. The assistant then spoke to the shop girl and said "yes"!!
After that Victoria continued to whisper to her assistant who in turn would speak to the shop girl assigned to them. She didn't speak at the till, just stood there glaring at my friend while her purchases were wrapped.
