After 2004 the queues for toilets became so long that the police had to regulate the entrance. To keep traffic moving through the restrooms, men headed for the toilets were directed to the "Pissoir" (giant enclosed grate) if they only needed to urinate. The number of toilets was increased in 2005 by 20%. Now approximately 1,800 toilets and urinals are available.
Many Oktoberfest guests visit the quiet stalls in order to use their cell phones. For this reason it was planned in the year 2005 to install a Faraday cage around the toilets and to prevent telephoning with a mobile telephone. However such constructions are not certified in Germany, and so instead signs were placed warning toilet users not to use cell phones in the stalls.
