Here in central/south Texas when you order iced tea at a mexican joint, it will usually come with a lime wedge. Everywhere else its a lemon wedge. You will also likely not be asked sweet or unsweet at a mexican place, like you will be elsewhere.
And I can vouch for TB, I have seen native mexicans put lime on damn near everything while eating. But of course I also dont think Ive ever see one roll up meat and other toppings inside a whole tortilla and eat it. They usually tear the tilla into pieces as they go and use it like a soft chip or an accompaniment to whatever else they are eating. Nor have often see them eating flour tillas, almost always corn.
