Whyfor Buc-ee's?
My favorite gas station Buc-ee's made an appearance in I'm Starting to Worry About This Black Box of Doom by Jason Pargin. He describes it as "an ostentatious mockery of a convenience store" and compares it to Walmart. But... Buc-ee's isn't popular because of its size.
No...
No...
No...
Nope...
No, no, no... That came after.
It's the bathrooms. Their bathrooms are immaculate. I remember when there was a little Buc-ee's the size of a normal gas station about two thirds of the way to Austin from Houston on 290. You'd always hold your pee if you were close.
Eventually you find the great rest stops of Central Texas, Hruška's, Prasek's, Czech Stop, but they can't compete with Buc-ee's. Buc-ee's bathrooms are unbeatable. Each one's the size of a handicapped restroom with a full door, a lock that visibly shows its status, and the red and green parking lights above each door to help guide you to an open stall. You can press a button to summon a janitor who is probably already cleaning the restrooms.
I haven't had a favorite gas station before, but they care about the details. Their car wash has a mirror to align your wheel with the conveyer belt. Who hasn't messed that up before? Love ya, Buc-ee's.
