El Centro Supermarket
8231 Park Ln, Dallas, TX 75231
The rudest worst people in retail grocery business.
My recommendation, unless you're Mexican don't go to this place.
Even if you're Mexican, there is no guarantee that the rude Mexican broads will serve you with common courtesy expected of a business establishment. They run the place not like an American based business establishment but like some third world mafia-financed barrio investment ready to rob you and send you crying.
My advice, unless you are just itching to be disrespected and treated like the lowest life form, avoid this place and patronize other surrounding businesses in the area.
