Be careful when you buy food here

I have been going to this outlets for months. They have the best fish in town. I send all my friends and colleagues there. Two weeks ago I went there to try the new Slider meal, which was one of the most humiliating experiences in my life. When I got there, an empty store but a crowd of staff standing at the counter, made jokes about me in their home language, which unfortunately couldnt fully understand. After the food was ready, they made me wait 15 minutes before calling me. When I got home, both burgers only had slimy lettuce and some mayo, without fish. My family wasdisgusted and I left red faced and angry. This story will follow me as far as I go, including my circle of 5000 fb friends. I feel this treatment was a personal attack and feel ashamed that I support a store that couldnt care less how their staff treat their clients!
