only whites are served?

Visiting Worcester for the weekend we decided to have breakfast at Dros, because we regular Dros occupants.<br> We've been to CW Dros before, from where we were seated we could see the Bar lady adding water to all the cooldrink, we were shocked but we weren't in the mood to spoil our night out and we didn't order any cooldrink. But the past weekend we went there, waiting 20min for a waiter to bring drinks, that was clearly diluted. and a hour later our food was still not done. A couple sitting at the table next to us left as well. The white waiter is running up and down serving white customers while we just get 'Ek's nou by julle'. We asked him when we will be getting our food and he couldn't respond, he then had to get \The Manager"because we were leaving and didn't pay for the water drinks"
