Sacred Haven of Debauchery

The number 13 is considered unlucky in European culture, and the fear of the number 13 is called triskaidekaphobia. Because of this, in some buildings, floors are numbered in such a way as not to upset triskaidekaphobes: after the 12th floor, the 14th floor may immediately follow, there may be floors 12A and 12B in the building, or the 13th floor may be called "+1". Sometimes this also applies to house and room numbers. In Italian opera theaters, there are no seats with this number, and on almost all ships, the 14th cabin immediately follows the 12th. Also, the 13th row is missing in airplanes (after the 12th row, the 14th row immediately follows). Due to the superstition of many pilots, there has never been an F-13 fighter in the USA. The YF-12 (prototype of the SR-71) was immediately followed by the F-14. In modern Formula 1 car races, there is no car with the number 13; after 12, 14 follows immediately, and so on.
