It’s a chain of gas stations along interstate highways, either mostly or entirely in the south. Many are contenders for, and one of them is, the world’s largest gas station— not hyperbole. One has 120 gas pumps and they do so much volume, they have a team of attendants running around outside to deal with card/pump problems. They’re open 24/7/365 and constantly have dozens of fresh, made on-site BBQ items and sides ready to go for very reasonable prices, roasted nuts and other snacky confections being made fresh constantly, plus a huge line of high quality prepackaged snacks, a full clothing store worth of merch bearing Buc-ee the beaver, and a separate convenience store that itself would make an incredible American gas station.
In Florida, driving up through Georgia, the billboard advertisements start 200 miles away.
Truly shocking thing is that it’s genuinely high quality (considering the venue) and reasonably priced. It’s exactly the sort of product American capitalism is supposed to produce, but almost never does.
There are lots of videos on YouTube.
