Cielito Lindo Restaurant

so as soon as i walked in with my children there was a man yelling and fighting with what seemed to be his wife or girlfriend at the front door of the restaurant, they were cussing... the hostess was incredibly polite and so was my waiter. turns out i found a hair in my enchiladas. i asked to speak to the manager and up comes the man who was yelling and fightinng with his wife or girlfriend at the front door. i let him know about the hair in my food but he offered absolutely nothing because i had already eaten off my plate. he seemed frustrated even though i was extremely polite, i just wanted some type of discount since i could not finish my food. thats when i realized how unprofessional the management was. he spoke to me rudely and the first thing i experienced was him fighting with his wife. that was the worst first impression. the manager was fernando i beleive. and on the way out i saw him drinking at the bar!!! it has literally been the most unprofessional atmosphere i have ever experienced at a restaurant!!
