Recently I placed a phone order with Viviana. I ordered a chilaquiles and a taco. When my son came back home from picking up the order, we discovered that he had been given tilapia and a taco. My son took the order back and explained to Viviana that we had ordered the Chilaquiles, not the tilapia. Viviana checked the tab, spoke to the other girl in the restaurant, and told my son that he had ordered the tilapia and that is what she gave him. Viviana didn't admit she was wrong, did not offer to replace the order, just stared at my son so he left.
When I called to question Viviana, she admitted finally that she got the order wrong, and to bring the order back, but the damage was done. Insinuating that your customers are liars is not good business practice!
