SO DISGUSTED AND DISSAPOINTED

I went to buy some food and the person who made the food made a mistake and did not put any meat. I wasn't feeling too well and I did not check it and only realised when I got back in my office. I then went back and requested the meat and the guy who served me said sorry with a **** smile. I then hear him speaking to another lady saying\She's crazy - i put the meat. She must have ate it\" REALLY??? I brought back the food with proof. How disrespectful can you be????? I'm right there!!!!!! Sies"
