MGM Resorts International

I went to Excalibur Hotel on 6/27/2020 and played their slot machines. I tried to cash a cash-out ticket from the slot machine at the cashier, the cashier name Reina treated me with full of racism and disrespectful behavior that should not be tolerated at all.
Reina used abusive languages to me when I requested all of my winnings to be cashed out in $20 bills, then Reina said "Huh, what's you're talking about? What babe? What [censored]?" Clearly, these languages showed me that Excalibur Hotel cage is not taking racism and respect to customers seriously. I will never come back to that hotel unless they terminate Reina.
Lastly, I tired to talk to Reina's supervisor, but the supervisor told me "Busy, I cannot handle." There was no place to tell any of the Excalibur employees that I was treated with racism and rude behaviors.

I want you to know that I am not going to tell you who I am at all, but here comes my complaint! Lady Gaga was singing 'Judas' and had a minor fall off a big robot contraption! She swung her leg around is what I read on the article and had a minor spill! I don't know what the heck her dancers were doing but at least kind of helped her! I don't understand they should have paid a little more attention of what she was doing because if that was a bad fall for Lady Gaga she would been hurt badly and that is poor safety even onstage. I think it should have been done this way! To have the two dancers helping her down and the other dancers keep dancing during her song! Yes it was happening onstage when this was happening in Park Theater in Las Vegas, Nevada! Safety is important on the Strip and not letting superstars getting hurt! It need to stop! I am not saying this to be mean! I just don't want them to get hurt! :(
