Sorry to burst your Texas bubble but it was true when I visited. I worked for TGI Friday's with the corporate office based in Texas. I was denied take out service at a local beer store and denied service in a TGI Fridays
as were my friends. The head of Human Resources told us that the Texas Liquor Control Board had a law that did not allow people with out of state lincenses to purchase or consume alcohol in Texas. It may not be in effect anymore, but the damage was done. Texas is just a bit of a better location than Salt Lake City in my mind.
I've lived in Texas for on an off for about 15 years, had an out of state license for the majority of the time, and have never experienced this. I've never even heard anything like this. Did you look really young? They may have just denied you because they thought the IDs were fake.
