Unwashed dishes AT GALLERIA MALL SPUR

So I went to this restaurant for the first time expecting better service. Although I left with full of anger and annoyed so before I started to order the food I ask for the water ok fine. They bring water with ice ,lemon. But there problems start when I look at the glass it was to dirty it looks like it was deeply put in a water where there was oil . It’s was so scary 😟 I ask for the stro ok they gave me .I order food they did again with a plate that is not full washed you can see that they only wipe it .no why and I ended up out of apetite. Spur from galleria mall Please do wash your dishes no way . And stop that thing of socialising during the working hour
