Worst service for a place not even too busy

I got to goldrgoldrush in cresta mall coz I really enjoy the performance on Friday the 17th November around 20h00. Waited for about 15min for a waiter to even get to me and the worst part she passes me like I'm nothing coz I looked young and I felt probably I was black coz she was attending to the table of white old people in front of me. Finally she gives me a menu and I waited for about 30min or more until I decided to go to the bar. Felt sooo humiliated coz I chose them out of Beter places in cresta and when I get to the bar she doesn't even apologizes or say something she just looks at me with his spectacles and it's a black lady......hope she becomes a waiter all her life. I've worked for restuarants all my working days and audited bigger places ....she wasn't ****** she just judged me coz of tips maybe and I made sure I tipped the bar man .....
