I'll add that InO churns out the food, it's typically hot and fresh, and the name is apt.
Whataburger, on the other hand, is the slowest "fast food" on the planet. It is known.
However, the phone app combined with curbside pickup, have really changed things. I can order on the app and know that whatever their time estimate is, add 10-15 minutes, and that's when I show up. Then I can just hit the curbside spots and completely avoid the drive-thru line. It's a game-changer.
