Pfffft. Texas was one of the worst.
Despite being the oldest of the group at 25, not one, but two different restaurants in Texas refused me alcohol on the basis they thought both my British Driving Licence (a biometric photo-ID) and my Passport were fake as they'd never heard of Britain.
That and the entire fucking state stinks of oil. You can smell it before you cross the state line, and the smell fades as you leave, it's bizarre.
