Very Important Person
A very important person (VIP) is a person who is accorded special privileges due to his or her status or importance.
Examples include celebrities, heads of state or heads of government, other politicians, major employers, high rollers, high-level corporate officers, wealthy individuals, or any other notable person who receives special treatment for any reason. The special treatment usually involves separation from common people, and a higher level of comfort or service. In some cases such as with tickets, VIP may be used as a title in a similar way to premium. These "VIP tickets" can be purchased by anyone, but still meaning separation from other customers, own security checks etc.
VIP syndrome is when a perceived VIP uses his/her status to influence a given professional to make unorthodox decisions under the pressure or presence of the individual.
The phenomenon can occur in any profession that has relationships with wealthy, famous, and powerful clients or patients, particularly medical or airline professions. One example is the 2010 Polish Air Force Tu-154 crash.
