Standing in line to purchase chips to play the gentleman in front of me is getting a cash advance, the employee working with him is the cage supervisor I'm next in line and this supervisor tells me that he is closing the window, I say why did you let me stand in line and not say something sooner at which time he says it's not his job,, I said you just worked the window and now it's not your job? Then he tells me if I want to argue with him he will have me thrown out,, I contacted Mike Black and he addressed the issue with a positive and professional response. This supervisor who refused to provide service to me represents Derby Lane in a disgraceful manner and is not an asset to this well run facility.
