I wish I can give this less than one star. I have been coming to this taco place for years I gave them a break for a while because of bad service and just being treated bad by one of the workers 3 years ago. But tonight was horrible, another incident with a cashier that rang me up call; who look like she was confused from the beginning of the whole transaction because I use my iPhone to pay for my food. I sat and waited for my order. I finally got my order and she tried to give me my bag through two other customers and a glass that covering the registers, so I asked her to bring my bag around the counter if she could and she slung my bag to me, she threw it to me. I still didn't say anything. I checked my bag for the correct order. And then I asked her if she could give me an extra sauce because they only gave me two sauces with five tacos. I would pay for more if she asked. The young lady walked away and didn't say anything, so I didn't know if she was going to get more sauces or not.. so I came to the counter I said excuse me may I please have some extra sauces, now she yells and say "I'm going to give it to you!" So I yelled back and said "well you didn't say anything and you threw my bag to me and I didn't say anything then". So instead of apologizing she said something about *****. And I said instead of being argumentative you can just apologize. She was still argumentative in front of The owner who knows me and knows that I have spent hundreds and hundreds of dollars in his establishment. He said NOTHING, instead he let another worker come (male)to me and asked me to stop being argumentative instead of asking her to apologize to me the customer. I know the customers are not always right, but she was extremely wrong. I will never ever go back to this place and I wish that everyone else would stop going to this place because they treat us horribly and still continue to take The communities money. I feel extremely disrespected this situation could've escalated all because they don't know how to tell their employee to apologize for horrible customer service in front of management being present that is not OK...
