Found a blond hair in my food and the Latin older female manager made a joke of the situation in front of the guest and the staff. Saying "it could of been from my guest!!" and to be happy I got 3.89 off of an total 18 dollar bill, almost excusing us; a short black hair male and brunette female of placing the hair there. I am beyond offended... I always patronized this business, it was my go to spot. but from this experience, my friends and I will never be come back. So disappointed, with the lack of maturity, professionalism and respect displayed today. I will be alerting the department of health.
