Texas - you'll get a cup filled with sugar, sugar, ice, sugar, water that was barely run through some tea leaves, and sugar. I always specify unsweet tea.
Sadly, it more of a nuisance than anything else to me now. It's like I just want to get to Home Depot and now I have to sit through the traffic it causes 24/7/365.
Also, as they continue to expand, it feels like the mystique is wearing off. They used to only be in the middle of nowhere and are a welcome site when traveling 4+ hours between major cities. When I'm just trying to get around town, I'd rather just go to and normal gas station, I can just pull in fill up and be on my way, without having to navigate a sea of pumps and people all over the place.
