I have been quite a few times and have never noticed any "posh people" showing off or talking down to others. There is always a mix of people from all parts of society and I would say the vast majority of people are just ordinary who once a year treat themselves to a brilliant show.The only thing I am going to do next year is pay a bit more for one of the grandstand seats as it is difficult to get a good trackside spot due to the large crowd!!
