Wimpy Kolonnade Retail - Disgusting service

We usually go the Wimpy in Kolonnade retail more than twice a month. The service we received on Monday (30 April 2018) was the worst we had ever received. There was only the manager at reception helping someone settle their bill. We waited for a few minutes without being attended to and decided to sit down at an available table, which still had dirty dishes on it, with condiments and salt and pepper splattered across the table. Again, we waited a few minutes until I went back to the reception table to request for a waitron to come and clear the table and at least take our order. The manager came, cleared the table, leaving some of the spills on the table and said someone will come and assist shortly. This did not happen after waiting for another 10 minutes. We then left. To say I am utterly shocked and disgusted at this type of service is an understatement. Especially considering that the restaurant was not unbearingly busy and I approached the manager to assist.
