Extremely disappointed

On 5 October 2017 at approximately 4pm, my girlfriend and I went to the Blueroute mall branch as we usually do. We love the sushi that's why it's our first choice, however, lately the service hasn't been great at all. Today, the guy who served us did not pay attention at all. Orders had to be repeated several times and he paid more attention to the (dare I say) white customer that was sitting in the restuarant while we (being coloured) had to wait on him. We paid by card and we even had to do that by ourselves. Because everythingis usually in order (and we were in a rush) we did a quick check of the ordered sushi and left. When we got home the soya sauce was missing. What is sushi without soya sauce?!.. I wouldn't usually complain, but its been going on for a while now and we are extremely disappointed as it is one of our favourite places. As a waitress i expect to recieve the same kind of well mannered treatment that I'd give my customers.
