Texas Roadhouse review: Employee

I am writing in regard to our waitress that we had this evening. We had good service till the very end when I paid and tipped her and was going to hand her cash prior to us exiting the table and thank her for the good service. But when she brought our receipt she said here is your receipt and maybe next time I can be of better service to you. I said oh no you did great and she said "Oh I did well you didn't show it by the amount you gave me and walked off. So we asked for a manager, but the manager never spoke to me directly. The waitress came back over and I said I am sorry but I asked to talk to a manager. The manager who should not be a manager came to the table and was scared to death to even speak to me. She had nothing to say and was sticking up for the waitress and I said it is all good I will contact Corp. cause you could care less about what just happened. This location is terrible, my potatoes was about the size of a golf ball maybe slightly bigger. I was in shock everyone else had very large potatoes, and the steak was over-seasoned as always. The remaining time we were there the waitress continued to walk by and look at us and roll her eyes. She was so rude and then when I asked for a manager when she did come back she said oh I'm so sorry that I can not help you she told me I needed to apologize and I said no not with your eye rolling and smart remarks to you make each time you walk by us. Our friends had never been to Texas Roadhouse and were shocked at her responses and remarks. I want a full refund and someone to contact me asap.
