As previously mentioned, this has happened before. The operative complaint of the Saudis is...'impudence'. A small gathering, quiet, with drinks, will be met with quiet (with rare exception). A loud, huge party of 400+ people, mixed, with booze, etc, is just....an insult to the culture, or impudence. These will always be met with severity, understandably...attendance at these, not expecting a firm response, is stupid. Sam.
