I deposit 10$ on slot and the lady next door, said it was her daughter slot machine and she had 20$... She was having a fit... I apologize multiple times and I asked and young lady next door if it was her or her sister... She just mumble... So the best resolution was pressing the service button. She called me stupid for pressing it.. He came and acknowledged her comments first and went said its ok.. And she misunderstand... But it was totally b.S. And it does not give you the right to judge person. She was very condasending like i'm steal her child money... The tech guy came in and was on her side of course without acknowledging my prospective. He assumed that person. Was right. I just give up on hope and gave on my 10$ and said god bless you to the lady... I am highly disappointed... There multiple occasions I encounter miserable bad behavior at twin by twin river...
