I'm an American and Texan born therefore we are in the habit of not caring about the differences between British English, American English, or Texas dialect for that matter.
The most important takeaway regarding being a Texans is that you refer to sodas properly as Coke's and never as Pop or God forbid you're one of those Pepsi people. Me personally, I using don't drink carbonated beverages without Sour Mash Whisky or Canadian Blended Whisky mixed in it. Otherwise is juice, coffee, or tea for me.
P.S. We don't put milk in our tea. Actually we would probably argue that nothing belongs in tea beyond sugar, ice, and lemons.
