My sister & I went to the casino and were treated very poorly. We went in to play but before sitting down we asked an employee if we could have water because we had been walking & it was hot outside. She stared at us before telling us she was busy & walked away. We decided not to stay & spent our money somewhere else. I don't want to think it was a race issue but the employee was a white female & we are brown hispanics.
