worse place ever

I normaly go to carnival city to gamble, not to win the jack pot but to have some fun but, that does not happen, it is as if they do something with the machines, one never win, when you do get the bonus you do not get anything, you either have to play the maximum bet to get something back, you also hear about random jack pot give a ways but, see no one win the money...winners know when to stop....please at that place you will never be a winner, at the duma machines you never win big the free spins are so bad if you are lucky you will get R7, what us the purpose of getting a bonus but win nothing, yet again someone must pay their electricity bill.
