your party is displeased with the service of the bar staff a magnificent 7 may be called.
this requires all 7 people to urinate into a pint glass. next place a bar coaster over the top of the glass, tip the glass upside down and place onto the bar. the coaster is then removed leaving the air locked urine in the glass.
the beauty of the magnificent 7 is that once a glass has been removed by the bar staff the urine will cover the bar and staff and after which the bar staff will realize there is still another 6 glasses to remove.
