It's one that Mount Airy Casino apparently violated 18 times in one day. The Pennsylvania Gaming Control Board Wednesday fined Mount Airy $25,000 for an Oct. 7 incident in which three bartenders served 27 drinks in nine hours to a man who was playing a table top slot machine in its Glass Bar, including 18 drinks after the man was visibly drunk. The man, whom the casino did not identify, ended up falling off his bar stool and resisting arrest by state police.
