Hi I understand it's generally better to avoid mentioning brand names, such as saying a "pint of Beer" instead of a "pint of Carling" in a book. It saves the editor at a potential publishers a lot of grief, correct? But, is it okay to mention novels and films in a book? Can I say things like, "I spot a guy in the corner, sipping tea, reading a copy of 1984 by George Orwell." Sorry if it's a dumb question.
