Machine offline again

Emperors what is going on, every time I go to the casino the machines go off line, I make a day of it once a week and pick up friends organised baby sitters and set off to spend the day, only to see the same problem like the few days before , long Que at the cashier and frustrated people trying to get their money and the machine off line again this is not the first time and I am now going somewhere else, so goodbye and I hope your It department gets toothache , what a wast of a day
