Today, I was served by a waiter whose impertinence isn't worthy of that position, compared to all the people there who are willing to treat customers well. I work in that sector and have never written a negative review before, except on this occasion. And I will not stay here, and that boy is going to eat his words and my hamburger, because thanks to him, I have been left without eating for not giving me the answer that my hamburger is gluten-free (WRONG BURGER, WITHOUT SIGNALING THAT IT IS GLUTEN-FREE, WITH THE NORMAL BUN WHICH COULD CAUSE ME A SEVERE ALLERGY, MISTREATMENT AND LACK OF KNOWLEDGE WHEN DEALING WITH THE ISSUE, LACK OF RESPECT, ABSURD AND SENSLESS ANSWERS AND SOLUTIONS..) And I could continue, I only hope that the boy is given a "call to attention", not the rest of the team, since I will make sure that he pays for his lack of empathy.
