Aztec Tires

Terrible business. Rude and hostile behavior from the male owner towards me female customer. Had a tire checked last month and had a man with me no charge. Today went in alone and the owner says in spanish charge her $3. I asked why when they didn't charge me before. Owner got loud and in broken english said because we don't work for free then started talking about me in spanish to his wife other owner. I said excuse me are you talking to me? He just got rudder and more hostile then told me he had done me a favor the times before....I was scared to the point that I was going to call the police, but would have had to wait with these people so I left.
