After a few wasted phone calls (no one has a clue about chips) I took a ride to the HR Checked the poker room cage no 50¢ chips occasionally you will find one or two there why I have no idea.They told me lighting bingo has them.Lighting bingo manager told me the do not and will no use them.I proeeded to the main cage they knew nothing about the 50¢ chip.Asked to speek to the cage manager I was told they have them but will not part with them.
