Hi All, my experience with dbar cafe is not very ...

Hi All, my experience with dbar cafe is not very positive. I called a staff member on 15/9/19 at around 9.45am sat morning to reserve a table for 4 since my sister and her friends, whose also a former naval officer wanted to have coffee together. The staff member told me that they don't do reservation but I could go there and it's empty.
I had lots of good reviews about dbar cafe so I persuaded my sister and her friends to go there. When we got there after terrible parking conditions it was packed with people. So I joined the queue in order to be served. I'm browned skin and When I got to the top of the queue the staff member told me that another lady who was behind me was before me who was white and I told no I was there first. So in order to get rid of me she told me that there is a table for 4 upstairs. No-one escorted me upstairs, when I went upstairs nothing was available.
I came downstairs and by this time rest of my friends were there. I felt bad. I stood waiting to be served and no-one helped. When I finally found a table for 4 down stairs downstairs without any help I was asked by a staff member to get up and move so she could sit someone else there who came way late after me. I can't forget how humiliated I felt at this stage and ashamed. I politely joined the queue again. Another staff member approached us and asked us to wait and WHEN someone has finished eating then we will get a table plus there is 45min wait on food. She took my phone number and left. It was 10.30am+ and by this time with heat building up, we gave up and left. We only wanted a good service but we got none. I felt humiliated. I work for nsw govt, my sister is a QA officer in sydney and my friends are naval officer and this wasnt the way we wanted to be served. I am not going back to dbar cafe and this business has now lost a customer along with others who will hopefully not go through what I went through. Thank you.
