Such poor service!

I went to Anat Canterbury Crossing this evening, desperately craving their chips with a little schwarma sauce. I ordered a Jumbo chips and asked to add a little tub of the sauce, the gentleman ***ner) said they don't sell the sauce separately, when I received the chips I asked to please add some sauce on top...to feed my pregnancy craving and he said No! Like seriously I offered to buy it and add it and still NO! Like seriously...this is why I will never go back, service is important, adding some sauce won't put you out of business...but this kind of service will!
