Taco Cabana review: poor customer service/unprofessional

11-21-2019 @ 632am . I went to Store #20259 yesterday around the same time and ordered 3 breakfast tacos. the person that took my order gave me a senior discount, without having to ask for it.. (I'm 73 years old). Today I went to the same store and ordered the same thing. After my order was placed, I looked at my receipt and noticed that I didn't receive my senior discount. I mentioned to the person who took my order that I didn't receive my senior discount. He then stated back that he doesn't give out discounts unless they ask for it.
This was abit odd and was very unprofessional. I asked him if he did't see my grey/white hair. Mine you I'm also a Vietnam Veteran, not that this matters. my point is that this person (wearing a blue shirt) Think his name tag said Gregory. I think that this person needs to be retrained in customer service and how to be a professional.
Needless to say that this is by far the worst experience that I have seen in many a year. I work for the Lonestar College Police Department and was in uniform at the time of this disgraceful attitude and rude manor. I asked him again if he was going to give me a discount. Again his reply was I have already rang up your order. What professional treats there customers this way.
