When we arrived at Ruby's Diner in the City of Commerce we were seated in the rear of the establishment. The Waitress took our order in a timely fashion. However about 20 minutes went by and about 3 other set of people had come in behind us. I looked up and the waitress was personally delievering waters to all three of the tables that came behind us and we had not gotten any of our drinks. So I flagged down another waitress to ask about my drinks and she brought the regular drinks we ordered( a shake and arnold palmer). Then i was able to get the attention of the original waitress I asked her if she forhot our waters. She told me dont you have drinks? refering to the regular drinks not the water that i was asking for. Then she walked off. I was able to get a hold of the manager. i spoke with the manager he apologized. However while speaking to him she was bring the appetiezers to the other tables that came behind us. I then told the manager that we were leaving. He did give me a coupon for two free meals and dessert but i wanted the food i order and to be treated with the same respect even with me being African American and the other being Hispanic.
